Mitchell, who missed basically all of last season after tearing his right ACL, sustained a left leg injury on Tuesday and will be withheld from the rest of spring practice.
The redshirt junior is expected to make a full recovery for preseason practice in August, according to UGA head athletic trainer Ron Courson.
"The good news is we think he’ll be ready by the summertime to be working and be 100 percent by the time camp starts," head coach Mark Richt said after Saturday's spring practice. "A lot of times the big question is are that going to happen or not. We don’t think it will cost him the season at all or even any camp for that matter."
