Jaguars head coach Doug Pederson confirmed Tuesday that Lawrence's right shoulder injury is an AC joint sprain, while noting that the quarterback is "progressing" but uncertain to be available for Sunday's game against the Panthers, Michael DiRocco of ESPN.com reports.

EDGE Analysis

In addition to not making any promises about Lawrence playing Sunday, Pederson was also unsure about the signal-caller being able to practice Wednesday in any fashion. According to Mark Long of the Associated Press, Pederson added that Lawrence is still dealing with soreness after exiting this past Sunday's 30-12 loss to the Buccaneers with the injury, so the Jaguars may be inclined to hold off on having the quarterback practice until more of the pain subsides. C.J. Beathard would be in line for the Week 17 start if Lawrence can't go, while the Jaguars signed Matt Barkley off the Giants' practice squad Tuesday to provide added depth to the position group.
