You better not blink if Mike Tyson connects during his bout with Jake Paul ... 'cause Chuck Liddell tells TMZ Sports a KO is guaranteed if an Iron Mike haymaker lands.
"As soon as Tyson hits him," the UFC legend said of the upcoming boxing match, "it's over."
Liddell didn't mince any words when giving his thoughts on the superfight out at LAX this month ... saying he believes even at 57 years old, Tyson's got to be the favorite.
As for why, the Iceman made it clear he's still a huge believer in the former heavyweight champ's hands.
