Defensive lineman Richard Seymour appears to now be officially on the clock. The Raiders sent Seymour the five-day letter, which means that the former Patriots lineman has five days to report to the team or be suspended, league sources told ESPN's Adam Schefter Thursday night. Once the Raiders sent the letter, it imposed a deadline on both sides, with plenty to lose for each. Oakland could lose the player it covets, and Seymour could lose a season of earning $3.685M.
