Keydrick Vincent was breathing heavy but not complaining after running sprints with the Carolina Panthers' other linemen near the end of Monday's summer school practices. Vincent, the Panthers' right guard, flashed his trademark smile and talked about how good it felt to be practicing with his teammates. After being the lone member of the offensive line to start each of the first 14 games, a groin injury kept him out for the final two games of the regular season and the Panthers' home playoff loss to Arizona, his former team. It was disappointing, said Vincent. We were on a roll at the end (of the season). But stuff happens. Thank God, everything's healed back up. Just to run around and be out here with the guys feels great. Source: The Charlotte Observer
