Carolina Panthers rookie wide receiver Dwayne Jarrett, the team's second-round draft pick in April, said Thursday he was on his way to Carolinas Medical Center to have an MRI on his right knee. Jarrett has missed the last two games. He said the injury is to his medial collateral ligament (MCL).

   Because Jarrett has been slow to respond, the medical staff wants to make certain it's nothing more serious than a strain.

   "They said I sprained it a little bit," Jarrett said. "But they want to see what else is going on down there."
