Running back Latavius Murray is at practice Thursday, which is notable because it means that he didn’t suffer a setback in his first practice, the day before, since he got cleared to return from the concussion he got against the Chiefs.

Raiders coach Tony Sparano said that he would wait to see how Murray bounced back after Wednesday’s practice before he started figuring out how to dole out the workload at running back.

Well, now that Murray appears ready to play Sunday against the 49ers, Sparano and offensive coordinator Greg Olson need to come up with a game plan for how to get Murray, Darren McFadden, Maurice Jones-Drew and Marcel Reece involved in the run game.

Murray rushed for 112 yards on four carries against the Chiefs on Nov. 20 before his night ended with a concussion that he suffered on his final carry. He also fumbled on that play.

To that end, Sparano said he hasn’t seen enough of Murray, who has 14 carries all season, to know what he can accomplish in a featured role. However, he is “curious” to find out, just as fans are curious to see if Murray is a better option than the two veterans ahead of him this season, as well as next season, when the job figures to be up for grabs.

McFadden is averaging 3.3 yards per carry this season, the same figure he finished with each of the past two seasons. Jones-Drew is at a career-worst 2.2. Murray is at 11.9, which, obviously is inflated quite a bit by the 90-yard run he had against the Chiefs.

Right offensive tackle Menelik Watson (foot, ankle) isn’t at practice once again. Therefore, it’s likely that Khalif Barnes is going to start against the 49ers, with Gabe Jackson regaining his job at left guard.

Tight end Brian Leonhardt (concussion) isn’t on the practice field again, as expected. It seems like a long-shot for Leonhardt to recover in time from his second concussion in two games to play against the 49ers.
