Vince Young is officially a professional football player again ... signing a standard one-year deal with the CFL's Saskatchewan Roughriders.
The 33-year-old ex-Texas Longhorns star -- who hasn't stepped foot on a football field as a player since 2011 -- vowed to return to the gridiron earlier this year, hiring big-time sports agent Leigh Steinberg.
No word on whether Young's being brought in to compete for the starting job ... but the Riders are clearly giving the guy a real shot.
