Jacksonville Jaguars quarterback Blaine Gabbert has a torn labrum in his left non-throwing shoulder, says ESPN.com.

Gabbert will get a second opinion on the injury from Dr. James Andrews, but he might not be able to play this week when the Jaguars face the Green Bay Packers. That would leave Chad Henne as the starter for the Jags. Henne was just 9 of 20 for 71 yards and was sacked three times against Oakland after coming off the bench.

The Jaguars are already without starting running back Maurice Jones-Drew, who could miss signiificant time with a foot injury.
