The New York Jets acquired running back Kevan Barlow from the San Francisco 49ers 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. On Aug. 14, the Jets traded for Browns running back Lee Suggs, hoping to get help with Curtis Martin out. But Suggs failed his physical 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.
