South Alabama QB Cole Garvin injures ankle versus Oklahoma State

MOBILE, Ala. -- South Alabama quarterback Cole Garvin injured his right ankle on the opening series against No. 11 Oklahoma State on Friday night.

Garvin went to the medical tent after the first series, when he was sacked on first down and was forced to run the ball on third.

Shortly after, he was taken toward the Jaguars' locker room on a cart.

Dallas Davis replaced him on South Alabama's second series.

Davis started 10 games last season, then missed spring practice while recovering from shoulder surgery.

Davis led the Sun Belt Conference in total offense last season and was second in passing yards per game.

Garvin won the starting job in preseason camp.
