Chiefs QB Green Out Indefinitely with Concussion

NFL.COM reports that Trent Green sustained a "very, very severe concussion" when his head was slammed into the ground by Cincinnati's Robert Geathers and will be hospitalized at least until Tuesday, the Kansas City Chiefs said.

"He's feeling much better," Chiefs president Carl Peterson said. "But he has a very kind-sized headache. Hopefully he'll be able to go home tomorrow."

The two-time Pro bowl quarterback will be listed as questionable this week at Denver. Peterson said he didn't know when Green might return.
