Texans' Ed Ingram: Questionable with knee issue

Ingram (knee) is questionable to return to Saturday's game against the Chargers.

Ingram exited the game with 52 seconds left in the second quarter after remaining on the turf for an extended period of time. The offensive guard may have re-aggravated a knee injury he sustained earlier in the season, and his ability to return to Saturday's contest is unknown.
