ESPN’s Adam Schefter is reporting (via Twitter) that Oakland will sign OT Langston Walker later today in a move to shore up their porous offensive line. Walker isn’t a superstar blocker by any means, but he should stabilize the position somewhat for the Raiders, which is more than they can say right now.

Walker was originally drafted by the Raiders before moving on to play in Buffalo. He was cut from the Bills roster early on this season, and has been looking for a new team since then.
