The league announced that Commissioner Paul Tagliabue will also consider imposing an additional fine on the 11-year veteran, who will miss Sunday's game against the Detroit Lions.
The NFL first disciplined him earlier this week for the hit on Carolina Panthers tight end Wesley Walls, but the Redskins appealed Wednesday. Carrier and Redskins director of player personnel Vinny Cerrato met with NFL officials in New York on Wednesday.
The Redskins refused to discuss the matter until Thursday.
Speaking after the final decision was made, Carrier denied it was a malicious hit.
"I play football, made a play on the ball, knocked the ball down, and me and the gentleman collided," he said. "I thought I'd at least show them what happened and go from there. But I've been through it enough times, and I know what to expect from the league."
The hit occurred late in the second quarter of Washington's 20-17 victory.
Carolina faced a second-and-goal at the 22, when quarterback Steve Beuerlein tried to hit Walls just inside the 10.
The ball was there, but Carrier jarred Walls from behind almost simultaneously to break up the pass.
Walls lay sprawled for several minutes but walked off the field.
Over the past decade Carrier has earned a reputation as one of the NFL's dirtiest players.
Last season, he was suspended for a game and fined $50,000 for a hit on Green Bay wide receiver Antonio Freeman.
In 1998, he was suspended for a game, costing him about $25,000, for a helmet-to-helmet hit that gave Tampa Bay's Brice Hunter a concussion.
