Lennox Lewis says he's relieved the Mike Tyson vs. Jake Paul clash will not be a sanctioned bout ... saying this weekend if it were one, he'd be worried for Paul's safety.
Lewis spoke about the upcoming superfight while out at the CSA sports memorabilia show on Sunday in Chantilly, Virginia ... and he made it clear, Paul should thank his lucky stars the guys will fight under exhibition rules.
Of course, punches will still be thrown when the two step in the ring -- but under non-sanctioned regulations, it's not expected to be nearly as competitive as it would've been if it were the opposite.
