Ben Affleck was forced to pull out of the World Series of Poker “Ante Up for Africa” at Rio in Las Vegas the other day with a migraine, sources said. But Shannon Elizabeth came in second to win $80,000, while professional poker player Phil Gordon took the top prize of $129,086, which he gave to Refugees International and Project Enough. Also there were event founders Annie Duke and Don Cheadle, Matt Damon and Montel Williams. Affleck told Page Six, “This is the one poker event I go to each year, and I didn’t even get to play.”
