Wallace, making his fourth consecutive start for Delhomme, was hurt when he was sacked by Falcons defensive end Jonathan Abraham. Wallace hopped off the field on his left foot before being evaluated by Cleveland's training staff. He walked gingerly to the locker room at halftime.
Delhomme came in for one play, completing a short pass to Chansi Stuckey.
There was no immediate word on the extent of Wallace's injury. He went 11-of-15 passing for 139 yards and one touchdown before being hurt.
