Allen breaks down Raiders' tape

X-rays of Oakland Raiders rookie quarterback Derek Carr’s sore ribs came back negative, though he is still concussed, according to coach Dennis Allen.

Allen said he did not expect an ankle injury suffered by strong safety Tyvon Branch, who missed 14 games last season with a broken fibula, to be serious. And Allen was also hopeful that safety Usama Young (quad) would come off the Physically Unable to Perform list Sunday and practice, though he was not as optimistic about DJ Hayden (foot) coming off the PUP list to practice this week, saying, “I don’t expect that.”

A sampling of other topics touched upon by Allen after he broke down the game tape on Saturday afternoon in a conference call with Bay Area reporters of the Raiders’ 27-26 exhibition victory over the Detroit Lions on Friday night.

On rookie left guard Gabe Jackson getting a lot of time with the first-team offense: “I thought he played exceptionally well. And you know what? I think he’s a guy that continues to get better every day. I think he’s beginning to be able to adjust to the different things that defenses are giving him. He’s a smart player and he’s got good instincts, both in the run game and the pass game.”

On the performance of the offensive line, which seemingly allowed starting quarterback Matt Schaub to take numerous shots: “I know probably to the naked eye it looked like there might be some pressure and anytime the quarterback gets pressure, the common idea is,' Oh my gosh, the offensive line.' Well, there’s a lot of elements that are involved in that. … I thought the offensive line was solid in protection.”

On if he anticipates Carr getting more time with the first-team offense against Green Bay in the third exhibition game: “I wouldn’t necesarrily anticipate that. I think our gameplan going in is to get some significant work for the ones because when you go into that fourth preseason game, they’re probably not going to get as much work. We’ll see a lot of Matt Schaub in this game.”

On if the Raiders are streamlining information for rookie linebacker Khalil Mack, who did not have a tackle until sacking Lions third-string quarterback Kellen Moore late in the third quarter: “Well, we’re doing a lot more with him in practice. So we really haven’t cut back on the things we’re asking him to do from a practice standpoint…I get a ton of questions about Khalil Mack and where is he at and, when you watch the tape, the sack totals, the tackles, sometimes those things can be a little but misleading. If you don’t have a lot of sacks or you don’t have a lot of tackles that doesn’t mean you’re not being a productive player. I thought Khalil this week ... was much improved from where he was last week, and I think we’re going to see a lot of good things out of Khalil Mack.

On oft-injured running back Darren McFadden: “I think Darren is probably running the ball as well as I’ve seen him run it since I’ve been here. I think he’s probably more explosive than I’ve seen him since I’ve been here. I think part of that is that he’s remained healthy throughout the offseason, throughout training camp. There haven’t been any kind of nicks or nagging little deals that have slowed him down. So, hopefully that trend will continue because I’ve seen a lot of positives in what he’s done in the running game.”
