Vikings WR Greg Lewis (concussion) is officially listed as questionable for Week 13 at home against Buffalo.

Lewis didn't practice on Friday, and remains a game-time decision as to whether he'll play on Sunday. With Percy Harvin's (questionable) migraines flaring up again, Lewis might be needed as WR depth behind Greg Camarillo if Harvin can't go.

Interim coach Leslie Frazier revealed that WR Greg Lewis sustained a concussion in Week 12.

With Lewis, Sidney Rice, and Percy Harvin all sitting out Thursday, Greg Camarillo ran with the starters. The Vikes don't seem to be overly concerned about their depth for Sunday's game.

If the season started today, Greg Lewis would be the Vikings' No. 3 receiver.

Assuming the Vikings don't add a receiver better than Javon Walker, Lewis will play as an outside receiver in three-wide sets, kicking Percy Harvin into the slot. Still, there's no sleeper value here. Lewis has poor size, speed and physicality.

Greg Lewis is expected to start Sunday's exhibition game against the 49ers.

With Sidney Rice (hip) and Percy Harvin (migraines) both out, Lewis is filling in. Once those two return to action, Lewis will resume his role as the No. 4 receiver directly behind Bernard Berrian.

Vikings WR Greg Lewis is the favorite for the No. 4 receiving job, but he'll have to hold off a couple younger players.

Jaymar Johnson and Logan Payne are Lewis' primary combatants. Lewis and Johnson have been practicing on the first team with Bernard Berrian with Sidney Rice and Percy Harvin unavailable, and Payne has "been able to impress." We still like Lewis to win the job here, but no one in this group is likely to make any sort of fantasy impact.
