ALAMEDA -- As the Raiders began the process of forming their 2014 roster Friday, quarterback Matt Schaub was not at their facility and dealing with a "personal issue.''
Raiders coach Dennis Allen, asked about the condition of Schaub's sore elbow on a conference call, said he hadn't talked with his quarterback.
"Matt's got a personal issue that he's been excused for and so I haven't had an opportunity to see him and I'm not sure exactly when that will be,'' Allen said. "He's got something that he's having to deal with right now.''
Allen said that while he expected to see Schaub on Monday when the club reconvenes after two days off and begins preparations for the regular-season opener, he declined further comment because the two had not spoken.
Schaub missed three days of practice heading into Thursday night's 41-31 exhibition win over the Seattle Seahawks. Allen said Schaub had thrown "on the side'' during that period but the quarterback's pregame routine at O.co Coliseum was limited to footwork and he made no throws.
In the meantime, rookie second-round pick Derek Carr led the Raiders to four touchdowns in four possessions, completing 11 of 13 passes for 143 yards, three touchdowns and presumably becoming a candidate to start the opener Sept. 7 on the road against the New York Jets.
"I think the biggest thing really is to check on Matt and see where Matt is health-wise,'' Allen said. "He was making some progress last week throwing on the side with trainers. I feel like he'll be ready to go but we need to see how he's feeling Monday when he gets here.''
Allen said "we'll know exactly what we're doing'' Monday with regard to a starting quarterback, but whether Allen will actually confirm it is another matter.
Last season, when Matt Flynn missed the fourth exhibition game with elbow tendinitis and lost his job to Terrelle Pryor, the Raiders attempted to take the secret all the way to kickoff against the Indianapolis Colts, although there were reports Pryor had won the job.
Asked if he would announce his starter early next week, Allen said, "I haven't given that any consideration at all, to be honest with you.''
While Allen praised Carr, he was more pleased with the work of the offense as a whole, in particular a 68-yard, 12-play drive against Seattle's first-team defense.
"It's a good defensive football team and they had nine of their 11 starters playing,'' Allen said. "Denarius Moore makes a heck of a reception on Richard Sherman, Latavius Murray has a couple of nice runs. We did a pretty good job on protection. There was a lot of (good) things with 10 other guys on the field.''
While the outside perception is that Carr would seem to be a slam-dunk starter, Allen said, "There's a lot of things that go into a performance. There's a lot of things that factor into the decision-making process. But I will say I was very pleased with what I saw out of Derek Carr last night.''
Allen felt good about the chances of linebacker Sio Moore (neck strain) being available this week, but wanted to wait and see until Monday on cornerbacks Chimdi Chekwa (knee) and Taiwan Jones (knee).
