Glenn has a "bone-on-bone" condition in the back of one of his knees

Terry Glenn has a "bone-on-bone" condition in the back of one of his knees. The injury report lists him as probable with a quadriceps injury.

We were hoping to retire the phrase "bone-on-bone" after Curtis Martin's retirement. Glenn's season, and the rest of his career, will be about pain management. It's very possible he can play well through the injury. Eventually, he may require microfracture surgery, which would likely end his career. Fantasy owners shouldn't count on Glenn being a consistent factor moving forward. His status for Week 10 remains uncertain.
