Lennox Lewis says he'd seriously consider getting back in the ring with Mike Tyson for a long-awaited rematch ... but only if there was a serious demand.
"If the public wanted it then we would probably talk," the former heavyweight champ tells TMZ Sports.
Lewis famously KO'd Tyson in the 8th round when they clashed in June 2002 -- despite Tyson making some wild threats in the build-up to the fight (remember, Tyson said he wanted to "eat" Lennox's children!?).
