Chiefs' Justin Houston: Questionable for Sunday

Houston (shoulder) is considered questionable for Sunday's game against the Falcons.

Analysis:

Houston's shoulder injury is a bit of a mystery, as he practiced in full on Wednesday before missing Thursday's session, and then returned Friday on a limited basis. He's coming off a three-sack performance, so the Chiefs certainly hope he'll be able to suit up on Sunday. If he's unable to play, however, Dee Ford (hamstring) and Frank Zombo figure to see expanded roles at outside linebacker.
