With Chuck Liddell still debating on whether or not to return to the Octagon and fight again ... his friend, Dana White, has a message for the UFC legend -- please don't.
If you saw the new "ESPN 30 for 30: Chuck & Tito," you probably noticed the final graphic at the end of the show said, "[Chuck] is undecided about his future as a fighter."
In other words, he's still contemplating taking another fight, despite losing 6 of his last 7 fights ... including a brutal 1st-round knockout loss to Tito Ortiz in 2018.
