Bills cornerback EJ Gaines out for Raiders with leg injury

ORCHARD PARK, N.Y. (AP) The Buffalo Bills will be without cornerback E.J. Gaines for Sunday's game against the Oakland Raiders because of a hamstring injury.

He was injured during a Week 7 win over Tampa Bay. Gaines has been Buffalo's No. 2 cornerback since arriving in a preseason trade with the Los Angeles Rams. He has 24 tackles, one interception and two forced fumbles in five games.

The Raiders are coming off their best passing game of the season, throwing for 417 yards in a 31-30 win over Kansas City.

Buffalo will be without tight end Charles Clay (knee) and linebacker Ramon Humber (thumb). Safety Jordan Poyer (knee) and Richie Incognito (ankle) are expected to be game-time decisions.

Bills coach Sean McDermott says he's ''aware'' of Anquan Boldin's interest in potentially returning to the NFL but declined to elaborate. The Bills signed the 37-year-old Boldin in August but he abruptly retired two weeks later.
