There was a brief injury scare late in practice Tuesday when Percy Harvin limped off the field and then into the locker room, but it turns out Harvin only had gotten stepped on and was not seriously injured.

“He got stepped on,” Seahawks coach Pete Carroll said. “He got stepped on the back of his heel and got scraped up pretty good. He’s OK though.”

In fact Harvin returned just before the end of practice and took part in the final play.

—On a non-football related topic, Carroll was asked about the death of actor and comedian Robin Williams, his classmate at Redwood High School in Larkspur, Calif.

“It’s a tremendous loss,” Carroll said. “We were not real close. We were in the same graduating class and all of that, but everybody knew that he was there. It’s a huge loss. What an extraordinary person and character he’s been. He’s been so constantly great for so long, it’s just a terrible loss. For everybody who loved him so much, it’s really a hard day.”

—Asked about Marshawn Lynch being named in a police investigation—allegations the team called “bogus” in a statement Tuesday, Carroll only said he’s going with that team statement.

“I’m just going along with the statement that we made for right now,” he said. “I’ll just support whatever the statement was from the club.”

Asked about Lynch’s day on the field, Carroll said, “Very good. Very good today.”

—For the first in camp, the Seahawks had their entire starting line on the field—from left to right, Russell Okung, James Carpenter, Max Unger, JR Sweezy and Justin Britt.

“It’s really good,” Carroll said. “That’s the first time really it felt like we had everybody on the field at the same time. I think Russell got a little tired today, he got his first big dose of work, but he did well. It was great to have James and Max and everybody going. It really feels good for us to see that we’re going to start the process of that continuity that’s so important to us.”

Carroll said it’s too early to know if all of them will play in Friday’s preseason game. Okung is probably the least likely to play, as he is just now getting something close to a full workload after missing the start of camp recovering from foot surgery.

—Safety Kam Chancellor, another player coming back from surgery, has his most active practice and for the first time got work with the starting defense in 11-on-11 drills.

“He’s back out there,” Carroll said. “He’s finally getting some reps. It’s really good to see him and Earl work together. The other guys can feel, Kam is such a big factor, he affects everybody, so it’s great to have him back out.”

As much as the Seahawks like having Chancellor back, Carroll said they’ll take their time working him in: “We’re just going to go one day at a time, see how he’s doing. There’s no reason to rush. We’ve got plenty of time to get him back, and the fact that he’s back out there practicing today was really good. Now we’ll see about tomorrow and just go one day at a time.”

—On the backup QB battle between Tarvaris Jackson and Terrelle Pryor, Carroll said it is “too early to make any statement,” on the competition, though he noted that “both guys performed well,” and said when it comes to Pryor, “We have a lot more to learn about Terrelle because we don’t know as much about him.”

The Seahawks continue to be without several injured linebackers, though rookie Kevin Pierre-Louis was back from an oblique injury. Carroll said Malcolm Smith (ankle) “is a little bit ahead” of Korey Toomer and Bobby Wagner, who both have hamstring injuries. Carroll said Wagner is “getting real close.”
