Raiders sign tackle Tony Hills Posted by Mike Wilkening on August 20, 2013, 2:46 PM EDT Getty Images The Raiders, whose offensive line struggled mightily in their last preseason game, have signed ex-Bills tackle Tony Hills, the team said Tuesday. In a corresponding transaction, the Raiders waived/injured kicker Eddy Carmona. Hills, 28, has appeared in 10 regular-season games since entering the NFL with Pittsbrugh in 2008. He played in six regular-season games for Indianapolis in 2012, starting one game as an extra tight end. The Bills released Hills, whom they signed in July, on Sunday. Hills could compete for a reserve role with the Raiders, who allowed seven sacks in Friday’s preseason loss at New Orleans. The club recently lost starting left tackle Jared Veldheer to a triceps injury that is likely to cost him at least part of the season, leaving Alex Barron as the current starter on the left side.
