A teenage football player says he's truly sorry for trash-talking Cam Newton at a camp over the weekend ... explaining, "I never meant to humiliate & let anyone down."
If you missed it, the young footballer and the former NFL MVP really got into it at a 7-on-7 event in Myrtle Beach, SC.
Cameras caught the player calling Cam "ass" and ribbing the 33-year-old for being an upcoming free agent.
Cam -- who helped sponsor teams at the event -- responded by telling the kid he was "rich" and asking to see his parents.
