Wilson was added to the team on Monday. He will be the sixth Seahawks player in the game, joining offensive linemen Max Unger and Russell Okung, running back Marshawn Lynch, safety Earl Thomas and kick returner Leon Washington.
Wilson threw for 3,118 yards and tied the NFL rookie record with 26 passing touchdowns in the regular season. His finest performance of the year came in Seattle's NFC playoff loss at Atlanta where Wilson threw for 385 yards and two touchdowns in the 30-28 loss.
Wilson was originally voted a third alternate for the NFC.
Ryan was injured in Sunday's NFC championship game loss to San Francisco.
