Matt Ryan -- Dominates Golf Tourney ... Wins Football Signed By Himself

Fun Fact -- The winners of the Matt Ryan Celebrity-Am Classic golf tourney get a football personally autographed by Atlanta Falcons QB Matt Ryan.

Funner Fact -- Matt Ryan's group won the tourney.

Don't worry, Matt ended up giving the prize to one of the kids at the Aflac Cancer Center at Children's Healthcare of Atlanta ... the organization that Matt was raising money for.

The kid is cancer survivor Justin Berry (who was also the keynote speaker at the event) -- and according to our friend Craig Sager Jr., Matty even personalized the ball for him.
