The MMA world was rocked with bad news today when it was revealed Saturday’s UFC 209 co-headliner between Khabib Nurmagomedov and Tony Ferguson was off.

Nurmagomedov (24-0 MMA, 8-0 UFC) was hospitalized due to a bad weight cut ahead of today’s official weigh-ins and therefor h is scheduled interim UFC lightweight title clash with Ferguson (22-3 MMA, 12-1 UFC) was scrapped.

It was the third time the fight between the two contenders has gone awry, and as a result UFC 209 lost arguably its most anticipated fight.

Check below for the top Twitter reactions to the lost UFC 209 co-main event.

Weight cutting is the biggest problem in MMA. We need a solution where we transition towards fighters competing at their actual weight. — Joe Rogan (@joerogan) March 3, 2017

To severely dehydrated yourself 24 hours before a cage fight is insane and has massive health and performance consequences. — Joe Rogan (@joerogan) March 3, 2017

If Khabib can't make it to weigh in's, I know a lightweight that would love a rematch against Ferguson. 😉 — Brandon Gibson (@SixGunGibson) March 3, 2017

Remember Conor saying he couldn't commit to a fight with Khabib because he has problems making it to the fight? — Matheus Aquino (@MatheusDCAquino) March 3, 2017

Hearing that @TeamKhabib is in the hospital and might not make weigh ins. Weight cutting is the absolute worst problem in MMA. — Chad Laprise (@ChadLaprise) March 3, 2017
