What does Sherdog want? Like, you want Yan to win so you expect Aljo to shake off a hard knee to the head that he wasn't expecting and get up in a compromised condition to get finished by Yan? Yan fucked up. Stop defending Yan. He's the one who threw the strike. If someone knees you in the head, they get a HUGE advantage going forward. There's no way to shake that off in a few minutes. At that level where they are both so evenly matched, that edge is certain doom if Aljo continues.
Put it this way, who has won after deciding to continue after a massive foul like that? Maybe there has been, but I don't remember it. I can remember many who have lost though.
