The length of time Jenkins will be out will be determined by the grade of his particular injury.
For a grade 1 or 2, a player should be relatively pain-free and could return to workouts within two to eight weeks, but he will still require rehabilitation to avoid re-injury or further long-term damage to the joint.
For a grade 3 or worse, or what is deemed a complete separation of the shoulder, referral to an orthopedic surgeon to discuss treatment/rehab options would be recommended and, in some cases, it can take anywhere from two weeks to six months for a player to regain full mobility—some never again are able to do what they did without some level of pain being experienced.
Sam Bradford, former Oklahoma Sooner quarterback, suffered a similar injury in his senior season and it kept him out for the better part of the year after he attempted to come back too soon and re-injured the same shoulder early in a game.
Hopefully Jenkins' prognosis is a good one as Georgia's depth would take a big hit if they were to lose him for any substantial period of time.
