I just re-watched his snaps, he 100% hurt his left knee (buckled under him a little oddly as he went to the ground) on his 20 yard grab which means he scored his 40 yard TD on said bum knee. Again, I'm not overly concerned but I wouldn't be surprised if he missed some practice time this week.
I am honestly amazed, year in and year out, at the pain tolerance of the average NFL player. Pretty much everyone is banged up at one point or another during a season. It is a violent game played at high speeds. But these guys get treatment and just push through it.
Think about how many times you see a Megatron or Marshall or ADP limp off and it's oh #### no please don't be hurt and next thing you know they're back out there making a play. Or they're limited all week but come Sunday they're getting it done.
It's fashionable to be nonchalant and cynical about the NFL, but I really am in awe of how quickly these guys recover.
The HC didn't seem to think it was a big deal yesterday, but he definitely tweaked something. Limited practice would be a good thing IMO.
