These workouts are voluntary, and Clemons was not present for the team's workout last Thursday, which was open to the media.

What that has done is open an opportunity for rookie Bruce Irvin, the team's first-round pick, who looked very fast off the edge and during one pass rush, showed a great change of direction, catching the offensive tackle off balance and ducking inside.

Irvin, 24, was slated to step into the role Raheem Brock filled the past two years as a backup defensive end and staple of the third-down pass-rush package.

Clemons has started at defensive end the past two years, recording 22 sacks. He is 30, and entering the final year of his contract, which calls for him to make $4 million in salary.

Again, these workouts are voluntary, but Clemons' absence has given Irvin more looks with the first-unit defense.

• WR Kris Durham worked out without a red jersey, denoting he was not protected. He is coming off shoulder injury he underwent last year to repair his labrum.

• G John Moffitt worked as the center with the third-team offensive line.

• G Deuce Lutui is a shadow of his former self. A significant shadow, listed at 338 pounds, but nowhere what he weighed at the start of training camp the past two years.

The Seahawks have set a weight guideline for Lutui that he must be under 350 pounds, and he has modified his diet significantly to the point that he was vegan for a period of time.

That makes Max Unger a little suspicious, though.

"He said, 'for a period of time,' " Unger said. Well, according to that logic, Unger said he might consider himself a vegan for a (brief) period of time.

"I haven't eaten for three hours," Unger said.

• WR Golden Tate continued to watch practice after suffering a hand injury last week.

• S Winston Guy participated in practice, wearing a red jersey. The team's sixth-round pick, he did not participate in the team's three-day rookie minicamp as he was recovering from a shoulder injury. Guy intercepted a pass during Wednesday's workout.

• TE Kellen Winslow made an incredible diving catch right on the sidelines, and engaged in some woofing with Seattle's first-unit secondary, which was on the sidelines right where Winslow made the catch.
