The Raiders designated Runyon (lower body) for return to practice from their injured reserve list Wednesday.
Per Ryan McFadden of ESPN.com, it's a lower body injury that Runyon has been dealing with since late August that has kept him out for the first five games of the year. Las Vegas now has 21 days to officially activate Runyon before he'd have to spend the rest of the season on IR, and given that he was in pads for practice Wednesday, he seems like a good bet to return to action soon.
