Probably not.
Men that look like Sean O'Malley can't stuff takedowns.
I forget who I heard talk about it recently but they said they have little hope for O'Malley vs Aljo, that O'Malley outspokenly chose to avoid tougher tests and wrestlers, so we haven't even seen him face a guy like Aljo yet. And that it could be a disservice to himself, you need those tough tests and different looks.
Petr Yan was a pretty tough test. He didn't really pass it with flying colours but he definitely showed he's game.
Seems unlikely.
I think the real question is if he can get back up.
