His agent, Darin Morgan, said Jarrett's car was rear-ended on Interstate 77 near Charlotte, N.C., and Jarrett was able to walk away. He has bumps and bruises.
"Dwayne is fine," Panthers General Manager Marty Hurney told the Charlotte Observer. "I don't have all the details yet but he's fine."
Jarrett was Carolina's second-round pick in this year's NFL draft out of Southern California.
At USC, he had 216 receptions for 3,138 yards, becoming the third player in school history with at least 3,000 receiving yards. Jarrett caught at least one pass in every game in which he played, and established the Pac-10 Conference mark with 41 touchdown receptions.
