I've not seen the fight. But from what I have read it sounds like he was battering Holloway standing up until he hurt his knee. Makes good sense to try and take it to the floor.
Fuck in hell though. Getting a take down at that level is no joke even if you are 100%. Can't imagine the pain of shooting full power on a good opponent with a dodgy knee.
How many did he hit? Were they decisive or did he have to spend a lot of time dragging him to the floor?
i hope it is not too bad that that he makes a strong recovery.
