Thornton (hamstring) was a full participant at practice Wednesday, Anthony Galaviz of The Fresno Bee reports.
The Raiders designated Thornton for return to practice from their injured reserve list Wednesday, and it appears he may be close to being officially activated. The fact that free-agent acquisitions Jalen Nailor (concussion) and Cody White (ankle) are tending to injuries could give Las Vegas additional incentive to get Thornton ready for game action sooner than later.
