Rookie running back Rashaad Penny had surgery on a broken finger Wednesday, a procedure that "worked out beautifully" according to Seahawks coach Pete Carroll.

The injury appears to be only a minor setback for the first-round pick out of San Diego State, who is expected to be back for the regular-season opener.

"He was in a pass-rush drill and he just caught his finger," Carroll said. "He had surgery that worked out beautifully. It's a couple weeks, he can already move it, he's not in a cast or any of that kind of stuff, so he's in pretty good shape. We got a great report on it; he's not going to be out very long at all."

Because of the play of other backs, including Chris Carson, who started the preseason opener, Carroll noted, "we still feel strong about what we have," at running back, even with Penny temporarily sidelined. "At this point we're OK. We're in good shape."

Carroll also said that the Seahawks have seen enough of Penny in two-plus weeks of camp to know what kind of player they acquired, even if he now will miss some practice time and preseason action.

"I don't have any doubt of what he's capable of doing, I really don't," he said. "We've just got to make sure he's in great shape, and let him play ball. He has shown us all the instincts, his want-to is great, his learning ability is excellent. He has applied himself in his pass-protection stuff, which he knew was something he had to work out, he has really applied himself—he'll get better at that in time, he's not as good as he will be—but carrying the football instinctively, how to catch it and run with it, he has done all that stuff. We've seen plenty."

In other running back injury news, C.J. Prosise was back on the field after missing last week's game and two days of practice this week with a hip-flexor injury. Mike Davis, however, was not on the field Wednesday because of a toe injury.

"He did all the early part of practice," Carroll said of Prosise. "He's on the verge on being ready to play this week now."

On Davis, Carroll said, "He's got a sore toe that just popped up today. He didn't even know he had it until he got out here and tried to run today. So I don't have much to report on it, but he's got a sore great toe."

Defensive end Frank Clark, who was limited early in camp due to offseason wrist surgery, has returned to full practice this week and could make his preseason debut on Saturday when the Seahawks play the Chargers.

"It's great to see Frankie out there going," Carroll said. "He's ready to go now, his wrist feels fine. He's back at it, and he'll have a chance to play this weekend."

Cornerback Byron Maxwell, who had been out with a hip-flexor injury, also returned to practice Wednesday.

"Maxie is going to try to play this weekend," Carroll said. "We'll see what happens tomorrow and the next day."

Second-year receiver Amara Darboh, who has also been dealing with a hip flexor injury, is "really close" to being ready to play in this week's game, Carroll said.

"He has been in the early part of practice the last couple of days, so it's like tomorrow they let him go or the next day. So he's close to being able to play this weekend, but he has to get on the field the whole practice the next couple of days to do that."

Asked for an update on defensive end Dion Jordan, who remains on the physically unable to perform list, Carroll said, "He's making progress, but it's still a while. It's still probably three weeks before we really make an assessment. It's probably that last week of preseason where we try to see if we can push for that and see how that goes. That's what we'd like to get done if we could."
