Spud Webb wiped the casino floor with a bunch of sports stars in a blackjack tourney Wednesday night -- but the best part ... all of his winnings are going to charity.
The ex-NBA star took on guys like Clinton Portis, Santana Moss, Ron Harper and Dr. J at the grand opening of the LIVE! Casino and Hotel in Maryland.
Webb was the last (and shortest) man standing when all the cards fell ... winning the $5,000 grand prize which he donated to the Boys & Girls Club.
The whole thing was pretty cool .
