While other teams look to limit their financial obligations to players with a lockout looming, the Raiders continued to spend Thursday, signing DT John Henderson to a two-year, $8 million deal, according to ESPN's Adam Schefter.

Henderson, a nine-year veteran, was due to become an unrestricted free agent.

Earlier in the day, Oakland reportedly signed CB Stanford Routt to a three-year deal that included $20 million guaranteed and placed the franchise tag — worth $10 million — on OLB Kamerion Wimbley.

Henderson signed with the Raiders before last season and played in nine games. He was sidelined for part of the year by a stress fracture in his foot.

The way we see it

The Raiders have focused on solidfying their defense with recent moves, and Henderson, when healthy, can help vs. the run. At 6-7, 335 pounds, the two-time Pro Bowler has great size, although his best days appear to be behind him.
