Thiago Santos continues to put the UFC light heavyweight division on notice.

Entering the Octagon against Jan Blachowicz in the main event of UFC Prague, the Brazilian looked to prove his recent success in his new weight class was no fluke. A little over two rounds into their contest on Saturday afternoon, Santos not only silenced his doubters but did so in violent fashion as he sparked Blachowicz with a crisp counter against the fence.

Check out the reaction to Santos’s victory below, plus the best of the rest from an action-packed card inside O2 Arena.

Thiago Santos def. Jan Blachowicz

Thiago is so damn explosive — Curtis Blaydes (@RazorBlaydes265) February 23, 2019

Wow the hammer is real — Belal Muhammad (@bullyb170) February 23, 2019

Underhook to a single would of kept him in the fight. #UFCPrague — Michael Chiesa (@MikeMav22) February 23, 2019

The ref gave Blachowicz every chance to recover but he was not having it. Covered up and showed that he was done fighting. What a shot from Santos that had to be! #UFCPrague — Aljamain Sterling (@FunkMaster_UFC) February 23, 2019

Santos is a monster #UFCPrague — éS (@EricSpicely) February 23, 2019

I went the distance with that savage. #UFCPrague pic.twitter.com/7NIzSlkvGC — The Mane Event™ (@EliasTheodorou) February 23, 2019

Great fight in the main event LHW is lit! #UFCPrague — Dominick Reyes (@DomReyes) February 23, 2019

Nice comeback by Struve it was looking rough first round #UFCPrague — Curtis Blaydes (@RazorBlaydes265) February 23, 2019

Struve continues to work his ground game and pulls off a triangle choke, while still in half-mount, for the sub win. #ufcprague pic.twitter.com/bjT7gD2SB9 — The Mane Event™ (@EliasTheodorou) February 23, 2019

Always love a Struve fight — Belal Muhammad (@bullyb170) February 23, 2019

Awesome fight big man @StefanStruve!! Way to go champ!! Time to live the good life #ufc #UFCPrague — Nik Lentz (@NikLentz) February 23, 2019

Struve says this may be his last fight, but isn't 100% on it. Is going to think on it. Win or lose, always liked seeing Struve in there. #ufcprague pic.twitter.com/o8izU1PnN0 — The Mane Event™ (@EliasTheodorou) February 23, 2019

Fuck — Aljamain Sterling (@FunkMaster_UFC) February 23, 2019

What a body shot! Not often you set that utilized in open stance #UFCPrague — Jeremy Kennedy (@JeremyKennedyWC) February 23, 2019

And just like that Ole hits the perfect liver shot and Gian is done. Wow. #UFCPrague pic.twitter.com/UacmOPWrO9 — The Mane Event™ (@EliasTheodorou) February 23, 2019

Just popped it on before Gian’s fight. For Liz how do you get to mount but leave her with her feet dug in the cage. That’s her only chase to bridge and sweep. Have to get head to the cage . — Chris Wade (@CWadeMMA) February 23, 2019

Pudilova really likes that axe kick, but gets rushed throwing one and is now down. #ufcprague pic.twitter.com/b3W8FTb6ro — The Mane Event™ (@EliasTheodorou) February 23, 2019

It's a cliche, but while Pudilova will lose this one, she'll learn a great deal from going three rounds with someone like Carmouche, in terms of toughness and tenacity. #UFCPrague pic.twitter.com/kXeVLk1Gbf — The Mane Event™ (@EliasTheodorou) February 23, 2019

Can’t believe they robbed that girl against Carmouche smh #UFCPrague — Curtis Blaydes (@RazorBlaydes265) February 23, 2019

Dodson drops Yan, while Dodson's hair goes full Sho'nuff. #ufcprague pic.twitter.com/0MNadF6RdE — The Mane Event™ (@EliasTheodorou) February 23, 2019

Save for Dodson's brief offence where he caught and dropped Yan, Yan pretty much owned the entire fight. #UFCPrague pic.twitter.com/IwS11oGcKp — The Mane Event™ (@EliasTheodorou) February 23, 2019

Wow Petr Yan is a dirty fighter #UFCPrague — Cub Swanson (@CubSwanson) February 23, 2019

Petr Yan is definitely a contender. That kid is good everywhere #UFcPrague — Chris Camozzi (@ChrisCamozzi) February 23, 2019

No mercy is a good nickname for that man. He is a killer! #UFCPrague — Tatiana Suarez (@TSPMMA115) February 23, 2019

Yan looked good. I’ve been keeping an eye on Mr No Mercy! Our paths may cross in the future but right now I got my eyes on a Number 1 contender fight! #Bantamweights #UFCPrague — Aljamain Sterling (@FunkMaster_UFC) February 23, 2019

Good scap so far! That nose though https://t.co/m37O7JqHeU — Devin Clark (@brownbearC) February 23, 2019
