http://sports.espn.go.com/nfl/news/story?id=3092097 I guess that bruised knee was worse than people thought. If it remains this painful for a long time it could definitely severely impact his playing ability - and by this report, perhaps even indefinitely. Big blow to the Colts. About 17 months ago I incurred blunt force trauma to my knee and ended up badly bruising the underside of my kneecap (my two bones hit so hard they bruised eachother) -- something that was shown on an MRI. The doctor said it would take 18 months to recover from, and literally only recently have I been able to do things without it hurting at all. The first few months when stuff pressed against it, it hurt so badly that I almost would fall over in pain. After that it was sore a lot and if hit moderately hard would be very painful. Eventually it was just sore, and now it's fine. If his injury is like that (and to be honest it sounds worse, as mine has gone away after 18 months, and they're saying his may never), it might be challenging for him to play on it (especially this week, but this whole season perhaps) even with shots for pain.
