Rex Grossman, playing in relief of an injured Brian Griese, threw a 59-yard go-ahead touchdown pass to Bernard Berrian with 3:11 to play as the Chicago Bears struggled to a 17-6 victory over the Oakland Raiders.
Cedric Benson tacked on an insurance touchdown with a 3-yard run with 1:39 to play as the Bears (4-5) sent the reeling Raiders (2-7) to their fifth consecutive defeat.
Grossman, who was benched following a 34-10 home loss to the Dallas Cowboys in Week Three, finished with modest stats - 7-of-14 for 142 yards and the TD - but delivered when it counted most to keep the Bears from fading into playoff oblivion.
The touchdown came just 52 seconds after Sebastian Janikowski had given the Raiders a 6-3 lead on a booming 52-yard field goal with 4:03 to play.
Defensive end Adewale Ogunleye then came up with the big play on defense, sacking Raiders quarterback Josh McCown and forcing a fumble that was recovered by Israel Idonije at the 3-yard line.
Benson burst into the end zone on the next play to cinch it for the Bears, who couldn't moved the ball throughout until the late flurry.
Griese was knocked out of the game with a left shoulder injury when he was sacked by linebacker Kirk Morrison with 1:32 left in the first half.
