The Raiders claimed defensive tackle Joe Cohen off waivers from Miami and waived cornerback Jason Horton.
Cohen, a fourth-round draft pick of the 49ers in 2007 out of Florida, gives the Raiders depth as they try to improve a run defense that has struggled in the first two exhibition games.
He suffered a season-ending knee injury during the 2007 exhibition season and was waived by the 49ers last year.
Horton (turf toe) was officially waived injured.
Eagles: Michael Vick will make his Eagles debut in a game in Philadelphia on Thursday. The quarterback is due at a bankruptcy court hearing in Newport News, Va., that morning but "he'll be here for the game" against Jacksonville, coach Andy Reid said.
Seahawks: Edgerrin James, the league's leading active rusher, signed a one-year contract with Seattle, a team spokesman confirmed. Earlier Tuesday, Seattle waived fellow veteran running back T.J. Duckett to clear roster space. James' deal is believed to be worth about $2 million, though agent Drew Rosenhaus did not immediately comment on financial terms.
Bills: Receiver Terrell Owens (sprained toe) still isn't ready to play, and running back Fred Jackson aggravated a thumb injury.
Rams: Wide receiver Donnie Avery, who had been expected to miss up to the first two weeks of the season with a left foot stress fracture, was back on the field. "I run fast, but I heal faster," joked Avery, who was hurt Aug. 7.
Steelers: Quarterback Ben Roethlisberger (foot injury) practiced, and coach Mike Tomlin said he'll play Saturday against Buffalo.
Patriots: New England sent veteran lineman Russ Hochstein to Denver for a 2010 seventh-round draft pick. The Patriots also released former Stanford safety Tank Williams.
Dolphins: Serena and Venus Williams are the latest celebrities to own a small stake in the franchise. Gloria and Emilio Estefan and Marc Anthony also recently bought small shares from owner Stephen Ross.
Etc.: Former Denver running back Floyd Little and Pittsburgh defensive coordinator Dick LeBeau, a former star defensive back, were named finalists for the Pro Football Hall of Fame by the hall's seniors committee.
