Louis Rankin flamed out after two games. Jonathan Holland failed to impress in his one-game stint. Justin Miller turned out to be a one-and-done experiment.
Now, it's Holland's turn again, with Gary Russell on deck, as the search goes on for someone to spark the Raiders' kick-return game.
The Raiders released Miller on Tuesday, one week after they re-signed him to take over for Holland on kick returns. Russell was signed to take Miller's place on the roster.
The Raiders need someone to fill in for Nick Miller until he returns from a broken right shin. Raiders coach Tom Cable said Miller is out for at least two more weeks.
Russell, 23, spent his first two NFL seasons with the Pittsburgh Steelers. He returned 16 kicks for an average of 23.2 yards last season. He said he is ready to bring back kicks for the Raiders, if asked.
His career figure surpasses the 18 averaged by Rankin, the 22 by Holland and the 17.7 by Justin Miller against the Houston Texans last Sunday.
Russell also slides into the No. 3 spot at running back, behind starter Michael Bush and backup Justin Fargas. Regular starter Darren McFadden is out 2-4 weeks with a torn meniscus in his knee.
"If they call on me to do it, I'll be more than glad to do it," Russell said of running the ball. "I know that Justin Fargas and Michael Bush are more than good (enough) for the job. I'm just here to help the team out."
Walker was released by the Buffalo Bills earlier this season after spending the past two seasons there. He spent his first five NFL seasons in Oakland after being selected in the second round of the 2002 NFL draft. He mostly was the starting right offensive tackle.
The Raiders are thin on the offensive line, with left guard Robert Gallery (leg) and right offensive tackle Cornell Green (calf) out with injuries. Erik Pears is slated to replace Green on Sunday against the Giants.
