The Panthers completed a three-day minicamp Sunday.  Quarterback Jake Delhomme, who is recovering from Tommy John surgery, was able to throw during the minicamp.  Delhomme threw on Friday and told reporters he has not had any setbacks from the surgery.  Coach John Fox says Delhomme looked good, but the team will continue to be cautious with him.  First-round draft choices Jonathan Stewart and Jeff Otah did not practice this weekend but still took part in meetings.  The Panthers will gather again for their summer school workouts later this month.
