Just an unfortunate ending to a hugely important fight. When they figured out they were LEGAL knees I think they would have immediately put them back in a clinch and carried on. Thing is I think Weidman was legitimately hurt (sounded groggy talking to rogan) so it would have been irresponsible to put him back in there from a doctors POV. Plus I think they had 2 doctors in there so it wasn't a decision made lightly.
I think a lot of us along with Dominick Cruz thought that second knee was illegal until we saw the slow motion replay from the 3rd angle, I don't think showing the replay and informing a referee of a wrong decision is a good idea because it just causes more confusion. At one point Miragliotta was telling Weidman 'I'm being told those knees were legal' and then telling him 'you have 3 minutes left'. Like I said I think he would have put them back together pretty soon after realising if the doctors hadn't come in and rightly stopped it.
The other thing is the actual ruling of a downed fighter, imo they should have 1 knee down at least to be classed as a 'downed fighter' otherwise you get guys trying to manipulate the rules - Weidman wasn't downed, he looked kinda gassed to me and he was looking for a break. I heard Mighty Mouse talking afterwards how he tried doing the same thing in his fight against Dodson and he got penalized for it so Weidman telling everyone he was putting his
hands down so he couldn't get kneed wasn't doing him any favours.
Just think how much more smoothly things would have gone if a) Weidman wasn't hurt and b) Miragliotta wasn't informed of the wrong call... Weidman would've taken a few minutes breather, Miragliotta would have incorrectly warned Mousasi for illegal knees and they would have continued and we wouldn't be talking about it. A series of unfortunate events I guess you could say.
