New York ? The New York Jets acquired running back Kevan Barlow from the San Francisco 49ers on Sunday for an undisclosed draft pick in 2007, their second attempt in a week to shore up the position.

The deal is contingent on Barlow passing a physical.

Last Monday, the Jets traded for Browns running back Lee Suggs, hoping to get help with Curtis Martin out. But Suggs failed his physical Tuesday and the deal was voided. The Jets are in desperate need of help at running back. Martin has been on the physically-unable-to-perform list since training camp opened with a lingering knee injury.

Though the 33-year-old Martin hopes to play again, his future is uncertain. The Jets have refused to disclose when Martin could return.
