He can play through the injury and most players do. but it would make sense to rest him this week regardless and save him for DEN, NYG and CIN where we will need him as close to his best as he can be.
Dont know why he needs a 2nd opinion if they know the injury and that he can play thru it. Its not like he HAS TO BE CLEARED TO PLAY. This is not a cuncussion where he needs to be cleared to play and practice. Here it is up to the team and player. My only guess for the 2nd opinion is that he wants to see if not resting can make the injury worse.
