ALAMEDA — The Raiders are starting to see some injuries pile up and were without several players at Wednesday’s practice, including running back Latavius Murray, tight end Clive Walford and linebacker Malcolm Smith.

Murray has been wearing a walking boot around the facility this week after getting banged up in Sunday’s win over the Baltimore Ravens. Walford left that game with a leg injury after taking a shot while going up for a reception in the end zone. He was on the side field catch passes with a sleeve on his right leg.

Smith also left Sunday’s game in the third quarter with a groin injury. He walked out to the practice field as the media viewing period was ending to serve as a spectator.

Returning to practice for the Raiders was right tackle Austin Howard, who missed the opener and the past two games with an ankle injury. Menelik Watson, however, still hasn’t practiced since suffering a calf injury in Week 3 against Tennessee.

Tackle Matt McCants practiced, as he did all last week, and running back Taiwan Jones was also on the field. He practiced twice last week in a limited capacity but he and McCants both were inactive for the game. Safety Nate Allen remained out after missing the final two practices of last week and Sunday’s game.

That’s all in addition to linebacker Ben Heeney and tight end Lee Smith, who were both placed on injured reserve this week.
