CHICAGO -- I don't have much to report on Johnny Knox's injury except that his night here is done.

Nor can I tekll you much about Charles "Peanut" Tillman, who left the field under even scarier circumstances: on a stretcher.

On the play Tillman was hurt, it was not obvious what he did. Let's hope he's OK. The press-box announcer is calling it a rib injury, which sounds harmless, but that could be any number of things, including a collapsed lung.

Knox went down after the Bears regained possession on offense and stayed down for a while with what has been called an ankle injury.

He was brought off the field by the cart, just before Jay Cutler said some words to him.

Reactionary guess is that Knox's season is done, but that's purely my uneducated speculation.
