Here is what went down in Fridays practice: Looks like we have our #2 Quarterback.

– Quarterback JaMarcus Russell is practicing and getting the strength back in his elbow, receiving the majority of the work as the undisputed No. 1 quarterback.

Meanwhile, Andrew Walter returned after missing practice with a tired arm the previous evening and finished off practice with a 99-yard drive culimnated in a 3-yard touchdown pass to Chaz Schilens on a fade route over Darrick Brown.

Walter got the offense out of trouble with a 38-yard strike down the left sideline, with Ronald Curry making a leaping circus catch despite decent coverage by Michael Waddell. A few gainers by Michael Bush and Darren McFadden set up a 29-yard jump-and-catch to Todd Watkins, putting the ball at the 5.

McFadden eventually got inside the 2 _ but here’s how practice works _ Kiffin didn’t want a short-yardage call, having covered that the previous evening.

“Move it back to the 3, I don’t want goal line,” he said.

Walter then finished it off with the flip to Schilens for the score.

For the first time, Kiffin conceded a clear-cut advantage for Walter over Marques Tuiasosopo as the backup quarterback.

“Andrew does everything you can out here. He continues to complete balls, and continues to have a high completion percentage,” Kiffin said. “I’d say right now he’s ahead of Tui. He’s making more plays and throwing the ball better downfield. Preseason will be big for those two.”

– Gerard Warren (thigh) missed his third practice and was joined by Terdell Sands, who had his knee drained. Sands, Kiffin said, will be reduced to one practice per day on double days. Warren remains day to day.

Also missing practice were John Bowie (knee) and Arman Shields (knee).

Shields, a fourth-round draft pick, has had some impressive moments but has it slowed by missing sessions as he works his surgically-repaired knee into shape.

– With Warren and Sands out, William Joseph got in work with the first string defense alongside Tommy Kelly. He broke into the backfield on one play and stopped Justin Fargas by latching on to his shirt. Joseph also showed up on several plays during the Thursday night session.

“He made a number of plays last night and it was good to see too because we had pads on when he was doing it and that’s what matters in the end,” Kiffin said. “He’s got to be more consistent in his play. He is powerful and big but he gets reached and cut off too much right now for us and that’s where we really need to improve him. He needs to be a more consistent player. He’s not played a lot of football since he’s been in the NFL.”

Joseph is a former first-round draft pick with the New York Giants who never reached his potential.

– Two plays served as a snapshot of what the Raiders hope to get from Kwame Harris at left tackle. On one play, he walled off Kalimba Edwards as Russell rolled out and found McFadden for a gain. On the next play, a counter with the action flowing to the right, Adimchinobe Echemandu cut back to his left and found Harris in front of him at the second level.

– The day’s most conspicuous drop came from Drisan James, as a Walter pass over the middle thudded off his hands and chest and to the ground.

– Only one jogger for a false start Friday _ center Jesse Boone.

– Training camp receiving stars come and go _ remember Alex Van Dyke and Will Buchanon? _ but it’s hard to escape the conclusion that Watkins isn’t making a serious run at a roster spot.

Kiffin said he was going over lists with staff members which rank players and that Watkins was showing up there as well as on the field.

“A number of guys on the staff had him extremely high on their list,” Kiffin said.

– Kiffin said Kelly weighs 330 pounds and is still rounding into game shape, but expressed hope that his presence at the “three technique” would shore up the NFL’s 31st ranked rushing defense. Kiffin liked what he saw of Kelly’s limited time inside as a Raider.

“He was extremely hard for guards to reach, more of knock-back player, kind of a two-gap scheme player in that sense even though that’s not what we play,” Kiffin said. “He’s an old-fashioned, head up and knock the guy straight backwards guy.”

– Tackle Mario Henderson took Kiffin’s criticisms of his development in stride, acknowledging he has a ways to go to be the player he wants to be. Kiffin said Thursday Henderson was not challenging for a starting spot on the right side and needed to develop in every area.

“I’m sure he’s probably trying to fire me up because that’s his job,” Henderson said. “I’m just coming out here to work every day. They’re the coaches, they know a lot better than I do. I still do have a lot to work on. So, that’s the one thing I got to do is just work hard.”

– One of the pitfalls of covering practice _ no official stats. I reported last night during a goal line drill about a ferocious collision in which Michael Bush came up short. Turns out, according to Kiffin, that Bush scored despite a perfect run fit from Kirk Morrison.

(Local officials hired for the practiced never raised their hands, not that I saw, anyway).

“The highlight of the drill to me was Michael Bush, him and Morrison were unblocked in the hole and that was our first chance to see what we’ve all hoped that Mike’s going to be,”’ Kiffin said. “He lowered his pads and ran over him and got us in the end zone.”

Bush, not surprisingly, was even more excited than Kiffin, given it was the closest thing to being in a real game he has had in nearly two years.

“It was the first time I strapped on top to bottom in pads and took contact like that,” Bush said. “It was a big collision, and I just enjoyed it. It was fun.”

Was Bush sure he had scored?

“I knew I got in. He met me right on the line,” Bush said. “I weigh more than him, a little bigger, and you could tell, and I got kind of got under him, so I knew I was in the end zone.”

– The Raiders got a lot of grief for deals which promised $18.125 million for Tommy Kelly and $16 million for Javon Walker, but at least those two figure to suit up this year.
