He left early in the game and did not return. Jason Worilds came in and played the rest of the way. From what I saw it didn't appear that Woodley was limping off the field when he left the game but it was a little hard to tell. After that he never returned and was on the sidelines without his helmet on.
I was a bit worried about him returning this week because the word was he was limping in practice from time to time this week. These hamstrings are tricky. At this point we don't know if it just stiffened up on him or he actually tweaked it again. Considering the score there was no reason to bring him back into the game anyway.
We have to be concerned at this point how much of a setback this will be for him.
Update - Tomlin's post game press conference he stated that Woodley felt a slight tweak so they pulled him for precautionary reasons so as not to risk further injury. He did not rule out Lamarr for Thursday night.
