Tennessee coach Butch Jones said earlier Tuesday that he would have "final confirmation" on starting quarterback Justin Worley's injury status within hours.
Jones is scheduled to meet with reporters at about 7 p.m. on Tuesday after the end of the team's practice session, and he is expected to confirm that freshman Josh Dobbs will start Saturday's game at Missouri.
The Sports Animal radio host Jimmy Hyams reported on Tuesday that starter Justin Worley would miss the next four weeks after surgery to repair torn ligaments in his right thumb.
The Vols (4-4, 1-3 SEC) play the Tigers (7-1, 3-1) on Saturday (TV: ESPN, 7 p.m.) at Faurot Field in Columbia.
Worley originally injured his thumb when he banged his throwing hand on the helmet of a South Carolina player on Oct. 19. His hand was wrapped last week against Alabama, but he appeared to reinjure the thumb when he threw an interception in the second quarter.
Worley sent out a tweet Monday morning that said, “Everything happens for a reason.” It was later deleted.
