ALAMEDA, Calif. (AP) The shelf life for running backs in the modern NFL is short. Get drafted, start playing and hope to get a second contract. By the time most backs reach their 30s, they're typically out of the league living in retirement.

Frank Gore and Marshawn Lynch are defying those odds, still producing at the respective ages of 35 and 32. The two will share a field on Sunday when Lynch's Oakland Raiders (0-2) visit Gore and the Miami Dolphins (2-0).

"That's my man. Marshawn is my man," Gore said this week. "I know him. He's a friend of mine. I love the way he plays the game of football. I'm happy that he came back because I knew that he still could play the game. I'm happy that a dude who came in back when I came in is still going. That's a plus for us."
