That's Tyreek Hill giving MAJOR props to Terrell Owens after the Hall of Famer ran a smoking 4.4 in the 40-yard dash during their race this month ... and yeah, T.O.'s still got it!!!

The NFL legend and the K.C. Chiefs superstar took to a high school field in Florida recently to settle a little racing bet.

Hill wagered $1,000 that even with a 10-step head start ... he wouldn't lose in a 100-yard sprint to Owens.

Turns out, though, T.O.'s still got jets -- even at 46 years old -- 'cause he won the race EASILY.

But, afterward, the two decided to get in a straight-up 40-yard dash ... and while Hill just barely beat out Owens there -- T.O. still clocked an INSANE 4.4!!!

Seriously ... watch the clip -- dude's got unreal speed!!!

That prompted Tyreek to heap some heavy praise on Owens ... saying T.O. was quicker than some of his Super Bowl champion teammates -- and that's when Owens made a pitch to Andy Reid!!

"I'm faster than half [the people] in the league!" Terrell said. "Andy Reid, trust me, if you get into trouble now, if you get in trouble, I'm letting you know right now, I'm social distancing, I got my mask on, but if you ready, it's going to be mask off. Bring me to Kansas City now!"
