And then there was one.

UFC 194 went down Saturday night from the MGM Grand in Las Vegas, Nevada and it certainly didn't disappoint. After nearly a year of build-up, Conor McGregor defeated longtime champion Jose Aldo to unify the UFC featherweight title with a first-round knockout. In the night's co-main event, former Strikeforce champ Luke Rockhold recovered from a trying first round to TKO Chris Weidman to become the UFC's new middleweight champion.

See how the pros reacted to all the action from UFC 194.

That reminded me of my fight with Aldo. He wanted it so bad, he was blind #UFC194 — Cub Swanson (@CubSwanson) December 13, 2015

#ANDNEW

Let's @LukeRockhold bring it home little brutha! — Josh Thomson (@THEREALPUNK) December 13, 2015

I think Rockhold just got a cold, hard dose of the reality of Weidman. #UFC194 — The Spartan (@EliasTheodorou) December 13, 2015

Rockhold looked so tense in the first couple of exchanges!? Still a good round. 1-0 to the champion #UFC194 — scott askham (@scottaskham1) December 13, 2015

Great rnd. Lot's of technique. Champ tkdwns to side mount vice guard/half were key — Brian Stann (@BrianStann) December 13, 2015

Weidman gets early back control. Eventually rockhold is on bottom with an arm in guillotine. Ref stand up. Weird. 1-0 Chris #ufc194 — Sarah Kaufman (@mmasarah) December 13, 2015

Lukehold taking this round with kicks. #UFC194 — The Spartan (@EliasTheodorou) December 13, 2015

#UFC194 That low and middle kicks are making great job. Rockhold is taking the lead. — Jan Blachowicz (@JanBlachowicz) December 13, 2015

Even blocking body kicks hurt, still steals some wind. Very effective adjustment by Rockhold — Brian Stann (@BrianStann) December 13, 2015

I got it 1-1 right now — James Vick (@JamesVickMMA) December 13, 2015

Both guys looking pretty tired by the end of rd 2. Rockhold utilized some nice kicks and landed his hands to make it now 1-1 #ufc194 — Sarah Kaufman (@mmasarah) December 13, 2015

Weidman owning the third so far. #UFC194 — The Spartan (@EliasTheodorou) December 13, 2015

These are the fights that make me love this sport. Clean hardworking athletes with corners that care about the sport #UFC194 #aka #longosera — Tim Kennedy (@TimKennedyMMA) December 13, 2015

Could've stopped that fight like 10 times #unreal #UFC194 — Derek Brunson (@DerekBrunson) December 13, 2015

50 unanswered punches?? Herb was waiting for a miracle — Chris Leben (@cripplerufc) December 13, 2015

Wtf omg!!! Weidman throws spinning back kick. Rockhold takes the back, gets mount. Throws everything but time runs out for the stop! #ufc194 — Sarah Kaufman (@mmasarah) December 13, 2015

@ChrisWeidmanUFC a bloody mess — Raquel Pennington (@RockyPMMA) December 13, 2015

@ChrisWeidmanUFC is a warrior ! — U R I A H H A L L (@UriahHallMMA) December 13, 2015

Man... I love Chris Weidman. But Luke Rockhold deserves every bit of that. #UFC194 — James Krause (@TheJamesKrause) December 13, 2015

Just as I thought. But I think Weidman single handedly gave it away with that hook kick he went for. Led to rockhold pouring it on! #UFC194 — Brad Tavares (@BradTavares) December 13, 2015

Wow. Exceptional performance by Luke Rockhold. So good everywhere. #UFC194 — Brian Stann (@BrianStann) December 13, 2015

He was destined for gold. #StrikeForceNeverDie — Tim Kennedy (@TimKennedyMMA) December 13, 2015

FENCE GRAB THAT TITLE SHOT

Anyone want to do an over/under on how #stool will play a roll in the Romero vs Jacare fight. #UFC194 #stoolgate — Tim Kennedy (@TimKennedyMMA) December 13, 2015

Red panty night starts now! Let's go gay Jesus. #UFC194 — Josh Samman (@JoshSamman) December 13, 2015

This is one I've been looking forward to. Have experienced the monster that is Jacare on the mat. Hope he pulls it out tonight — Jimmy Smith (@jimmysmithmma) December 13, 2015

These might be the 2 scariest guys on planet earth locked in a cage. #UFC194 #Jacare — Joe Ellenberger (@JoeEllenberger) December 13, 2015

Most people would have died from that spinning backfist #UFC194 — Nick Newell (@NotoriousNewell) December 13, 2015

Jacare waves him down and Romero accepts! Then hits him with heavy heavy ground and pound!! #UFC194 — scott askham (@scottaskham1) December 13, 2015

I guess fence-grabbing is legal tonight. #UFC194 — The Spartan (@EliasTheodorou) December 13, 2015

He is the biggest cheater. #UFC194 — Tim Kennedy (@TimKennedyMMA) December 13, 2015

Ugh ridiculous fence grab. Cmon — Brian Stann (@BrianStann) December 13, 2015

1 round each! Romero cheating again! Held the fence with everything he had to stop the take down! #UFC194 — scott askham (@scottaskham1) December 13, 2015

Romero looking tired at the end of rd 2. Held the cage to avoid a takedown but Goddard stood then back up. Close rd 2 #ufc194 — Sarah Kaufman (@mmasarah) December 13, 2015

Somebody throw Yoel a stool or another way to cheat. #UFC194 — Tim Kennedy (@TimKennedyMMA) December 13, 2015

Draw — Nick Newell (@NotoriousNewell) December 13, 2015

Great rd 3 for jacare. Chose to keep half guard to try and set up the head and arm but no finish. I think jacare will take it 29-28 #ufc194 — Sarah Kaufman (@mmasarah) December 13, 2015

Remero is a cheater in my eyes and I will never cheer for him again. — Sam Alvey (@smilensam) December 13, 2015

Come on!?!? — Dan Hardy (@danhardymma) December 13, 2015

Split decision for Romero. Rd 2 was for sure the deciding round and it was tough to score #ufc194 — Sarah Kaufman (@mmasarah) December 13, 2015

Yoel Romero clearly won that fight definitely not a split decision. I think Yoel can win the Middle weight title for sure!! @ufc — James Vick (@JamesVickMMA) December 13, 2015

Really 29-27??? Tough fight to call but 29-27 isn't right — Matt Brown (@IamTheImmortal) December 13, 2015

Jacare got robbed #UFC194 — Nam Phan (@NamPhanMMA) December 13, 2015

Interesting fight could of been a draw. Either way you're bat shit crazy if you think either one of them beats @ChrisWeidmanUFC #UFC194 — Brendan Schaub (@BrendanSchaub) December 13, 2015

Very questionable win for romero there. When I beat Mousasi, I should get the next shot! — michael (@bisping) December 13, 2015

Let me address this list. 3. Cheater 4. Fat PED user 5. Drinks piss 6. Very handsome 7. Already beat him #UFC194 pic.twitter.com/GAKCIutGQD — Tim Kennedy (@TimKennedyMMA) December 13, 2015

THE PROFESSOR

I'm excited to see the range of facial expressions Gunner Nelson displays in his fight tonight. #UFC194 — Tim Kennedy (@TimKennedyMMA) December 13, 2015

I think I'm taking Gunnar...I think #ufc194 — Sarah Kaufman (@mmasarah) December 13, 2015

Gunni super-psyched for this fight. Geez, calm down, dude. #UFC194 — The Spartan (@EliasTheodorou) December 13, 2015

I have to say @demianmaia is probably one of my most favorite #bjj fighters of all time. So excited for this @ufc welterweight bout #UFC194 — Alpha Cat Zingano (@CatZingano) December 13, 2015

been looking forward to this fight for months! may the best man win good luck — Rory MacDonald (@rory_macdonald) December 13, 2015

Striking will be on a milk carton for this fight! #UFC194 — Derek Brunson (@DerekBrunson) December 13, 2015

This is not a normal mount! This is the Juggernaut from the X-men holding you down with Thor's Hammer!!! #UFC194 — The Spartan (@EliasTheodorou) December 13, 2015

You can tell Gunnar Nelson has been working with a movement coach from that escape — Nick Newell (@NotoriousNewell) December 13, 2015

Awesome round. Demian Maia puts the position work on anybody! — Marcelino Evil (@KCBanditMMA) December 13, 2015

Maia's grappling is on another level. Plus 2. #UFC194 — James Krause (@TheJamesKrause) December 13, 2015

Gunnar's lack of jab / boxing and footwork on the feet is making this real easy for Maia . — Brian Rogers (@BRogthePredator) December 13, 2015

Demian Maia would be a major threat in a prison. #UFC194 #backcontrol — Tim Kennedy (@TimKennedyMMA) December 13, 2015

WTF is he doing just chilling, on his back, and getting elbowed!? #UFC194 Cmon Gunni!! — Aljamain Sterling (@FunkMaster_UFC) December 13, 2015

Could almost go 10-8 that rd for Maia as he got the back, landed great GNP, got mount then more GNP #ufc194 — Sarah Kaufman (@mmasarah) December 13, 2015

Maia is making me look like a clown with my prediction of Gunnar by tko. @clayguida just reminded me. #UFC194 — James Krause (@TheJamesKrause) December 13, 2015

So awesome to see two guys on the top of the "grappling in MMA" pedestal and then see that one guy is on a whole different level #UFC194 — Jimmy Quinlan (@JimmyCrashBJJ) December 13, 2015

Man, @demianmaia deserves more credit. Really a tough matchup for either winner of Condit/Lawler — Brian Stann (@BrianStann) December 13, 2015

I'm a big Gunnar fan, but that was bad. You can't not jab and back up vs Maia and expect to win. He made it easy on Maia tonight 0 pressure — Brian Rogers (@BRogthePredator) December 13, 2015

With 25sec left in the rd Maia looks at a camera and gives a peace sign and fiat pump knowing he's dominated 100% #ufc194 — Sarah Kaufman (@mmasarah) December 13, 2015

Never forget about @demianmaia ...it's a bad move. Wow, Maia is skill & efficiency personified. Amazing martial artist. #UFC194 — Kenny Florian (@kennyflorian) December 13, 2015





BLESSED

This should be a fun one :) #UFC194 — Cub Swanson (@CubSwanson) December 13, 2015

I like Max's mad face when he throws and lands. #UFC194 — The Spartan (@EliasTheodorou) December 13, 2015

I like to call @BlessedMMA, Mr Calm, Cool, & Collected! Love watching you fight stud! #UFC194 — Aljamain Sterling (@FunkMaster_UFC) December 13, 2015

20-18 Holloway ?? Just little faster to the punch — scott askham (@scottaskham1) December 13, 2015

Stephens' corner is right though: he needs a stoppage of some sort to win this. #UFC194 — The Spartan (@EliasTheodorou) December 13, 2015

I like the coaching in Stephens' corner. Urgency and F bombs. Rightfully so. #UFC194 — Josh Samman (@JoshSamman) December 13, 2015

Stevens is always in a fight because his power — Scott jorgensen (@Scottjorgensen) December 13, 2015

Max sliding just out of the way of those looping shots. Nice. #UFC194 — The Spartan (@EliasTheodorou) December 13, 2015

I really thought #Stephens would be more aggressive in this fight. Should be unanimous decision for #Holloway #UFC194 — Mike Ciesnolevicz (@MikeCies) December 13, 2015
