Matt Barkley won't throw at this week's NFL Scouting Combine, according to multiple reports.

Barkley, one of the top quarterback prospects for the April draft, had hoped to be a full participant in Indianapolis. Those plans, however, have changed as he's not yet been medically cleared to go through all the passing drills. Now he plans to showcase his skills to scouts at USC's pro day on March 27.

Barkley suffered a separated right shoulder in the Trojans' loss to rival UCLA on Nov. 17. That kept him out of both the regular-season finale against Notre Dame and the Sun Bowl against Georgia Tech at the end of last year.
