Having already dabbled in professional wrestling, Tampa Bay Buccaneers star Rob Gronkowski didn't shut the door on pursuing a boxing career down the road.
Gronkowski told TMZ Sports that boxing might be a good substitute for playing football to fill his competitive drive when he retires from the NFL. While acknowledging the work required to train for a new sport, he said it "would spark an interest."
The five-time Pro Bowler turns 32 on Friday, and his brief retirement from football was due in part to the wear and tear he accumulated through his first nine seasons in the league.
