Oregon Ducks running back will miss the 2015 season after shoulder surgery, reports CSN Northwest.
Tyner injured the shoulder last season during a kickoff return in the Ducks' seventh game of the season against Washington. He played through the injury the rest of the season, but "lingering pain and discomfort" necessitated the surgery, reports Fentress.
In his freshman season, Tyner was third on the team in rushing with 711 yards, and ran for nine touchdowns in 12 games.
Tyner, a junior, is expected to make a full recovery in time for next year.
