In an unsurprising move, Ahman Green was placed on IR today after it became apparent that the knee injury he suffered in Week 1 couldn't take game day activity. Undrafted Notre Dame running back, Darius Walker will be put on the active roster for the game against the Bucs this Sunday. Ron Dayne is expected to be the starter, though his time may be limited due to a minor ankle injury he suffered last week.Green suffered what was called a "knee bone bruise" in the game against Kansas City. He tried to come back from that injury, but had to leave games due to swelling and pain. As I discussed last September, a diagnosis of a bruised knee bone gave Texans fans no comfort because the description of the injury sounded very similar to the same thing that ended Texans running back Domanick (Davis) Williams' career.
You hear fans talk about a bruised knee bone like it is no big deal, as if it is bumping it into a coffee table. However, as I understand it, the knee bone is a place with not a lot of blood flow, and can be hard to heal. If you have more of a medical interest in in knee bone bruises, check out this link.

Domanick, Ahman, and Jamie: such promising sporting lives interrupted by what is a wussy sounding diagnosis, but actually is hard for doctors to treat, estimate healing time and determine its effect on future use.
