​The damage to Cory Sandhagen appears to be extensive thanks to Mario Bautista’s knee bar in their UFC 329 fight.Sandhagen lost by unanimous decision to Bautista in their pivotal bantamweight bout on the UFC 329 main card this past Saturday at T-Mobile Arena in Las Vegas. A key moment in the matchup happened in the first round when Bautista managed to lock Sandhagen in a knee bar that hyperextended his leg, which changed the complexion of the fight moving forward.AdvertisementAdvertisementAdvertisementAs it turns out, the damage wasn’t so much done to Sandhagen’s knee as it was his hamstring, which he shared Monday in an Instagram post that included a graphic photo.Pretty sure the knee bar tore my hamstring in the first (getting MRI this week). It kept locking out weird if I did certain things. So that kind of messed up my game plan.Congrats to Mario. He was well prepared. 1st was close but he won it with that knee bar. 2nd, I won (surprisingly cause leg was jacked). 3rd, I wanted to have the same round as before but got dropped. Gotta fight near perfect to win at the top. Something I need to get better at
