P.K. Subban learned the hard way Tuesday the turf ain't the ice ... 'cause the hockey superstar just got DUSTED by Terrell Owens in a sprint!!
It all went down at UCLA's track in Drake Stadium ... where the two gym rats decided to get a workout in.
At some point ... the stretching and hurdling moves turned toward sprinting -- and that's when the 44-year-old T.O. had to show the 29-year-old Subban the jets.
Owens jumps out to a big lead ... then cruises to the finish line -- leaving Subban with nothing left to say other than, "#Subbanator vs #halloffamer .... Hall of Fame always wins!"
Owens has been angling for a football comeback for a while now -- and after eating Owens' dust ... count Subban in as a believer.
