Matt Damon & Ben Affleck "Ante Up for Africa"

Matt Damon and Ben Affleck puts all their chips in for the “Ante Up for Africa” celebrity poker tournament during the World Series of Poker at the Rio Hotel & Casino in Las Vegas, Nevada on Thursday.

Proceeds from the event raised support for the Enough Project and the International Rescue Committee, benefiting survivors of the crisis in Darfur, Sudan.

Damon, 36, was knocked out within the first five minutes of the tournament. What (bad) luck!

“I’m here to try and raise money and awareness for the tragedies taking place,” he said. “I really hope it becomes an annual event. I hope it does and I hope it doesn’t. I hope we can solve this issue and refocus the efforts on something else in Africa.”

Affleck, 34, expressed how he doesn’t play much poker anymore because of his family. “I’ve got a kid [daughter Violet, 2] and I’m directing movies,” he said. “I have hardly any time now. Poker takes a lot of time if you want to stay good. I don’t want to suck. I was good. I’m still good. Family is better though.”

As of Monday, both of their families were still on vacation in Hawaii.
