(Undated) -- Two NFL running backs are clashing in the boxing ring. ESPN reports Adrian Peterson and Le'Veon Bell have each signed contracts to meet in a heavyweight boxing exhibition later this summer. The fight will take place on July 30th at Crypto-dot-com Arena in Los Angeles and marks the first time each athlete will compete in the ring. Both Peterson and Bell are currently free agents, but each played with multiple teams last season. Bell played eight games with the Ravens and Buccaneers, while Peterson suited up for a total of four games with the Titans and Seahawks.
