Here's a Ross Tucker article on CNNSI. He talks about how and why players play with injuries and what their teamates may think of them.

Here's the part where it sounds exactly like the Mike Williams saga in Buffalo. If this is about Williams, apparently his line mates felt exactly the same way about him as the fans did.
"One year in the NFL I started on an offensive line in which three guys, including myself, had surgery after the season for one thing or another. One of the two who didn't have surgery had missed parts of several games with a torn oblique yet still tried to play through the injury. The fifth member of the line, however, refused to play through a couple of minor injuries on multiple occasions. As a result he never really fit in with the rest of the group and was somewhat ostracized. The message was loud and clear as far as we were concerned: he could not be trusted to do the things the rest of us were willing to do for each other. And yes, as far as offensive lines go, I do believe that one bad apple can spoil the bunch."
