Tyreek Hill says it's put up or shut up time for Usain Bolt ... 'cause after the track legend talked some smack about the NFL star's speed, Hill officially challenged him to a race!
The scene played out in hilarious fashion Thursday ... after Bolt joined The Pat McAfee Show and mentioned Tyreek has urged him in the past to set up a race.
"Me and Tyreek Hill got into it," Bolt told McAfee, explaining it never happened because he says, quite frankly, his 40-time is just too damn electric.
