Jets coach Rex Ryan is challenging two of his players to slim down. Ryan, who underwent lap-band surgery two months ago, began a contest Monday with defensive tackle Kris Jenkins and offensive tackle Damien Woody to see who can lose the most weight by July 30. The coach told 1050 ESPN radio and the team's website that the winner will earn a donation to his favorite charity. "I just want to lose one more pound than those two," Ryan told ESPN. Ryan says he has lost about 40 pounds since the surgery. "The guys are going to have fun with it," the coach said. There's an offensive player, a defensive player and a 47-year-old coach. The handicappers, I don't know how they're going to view this."
