i just watched the play again to see where Meriweather got hurt. It was the play before he was limping and took himself out the game. The play was a run to Dunn up the middle and Meriweather came up and put a nice smack on him, during the end of the tackle Seymour was on Meriweathers back and kinda landed on him. It looked like his knees were fine, they werent hit blindsided from the side or anything, they were pretty much straight and he landed after the tackle on them fine. It looks like he twisted his right ankle at the begining of the tackle, it was hard to see but that was why he was limping on his right foot the next play, then he took himself out. I think he has a right ankle sprain, i dont think its very serious.
