Well, former Raiders defensive lineman Richard Seymour made a valiant effort in the 2014 World Series of Poker. He lasted well into day two but was ousted with some pretty bad luck.
Here's how it went down according to Pokerlistings.com:
Seymour opened with A♦ J♠ and three other players came along for the ride. He then moved all-in after the A♠ A♣ T♣ flop.
Raj Vohra was the only caller and he was behind with A♥ 7♥. Seymour faded the turn but lost to one of Vohra's three-outs on the 7♠ river.
Seymour didn't last into the prize winning numbers. He would have had to have been within the final 693 or better to take home any prize money. Even so, he outlasted some 4500 plus poker players. The Main Event began with 6,683 entries and Seymour stuck around into the final 2000 players.
He sported his Raiders hat for both of his days in the tournament. I expect he will be back to try again next year as well.
