Free safety Earl Thomas, who's recovering from offseason shoulder surgery after a hit he gave in this past January's NFC Championship win over the Green Bay Packers, was one of four Seahawks to start training camp on the team's physically unable to perform (PUP) list.

Thomas was activated from PUP five days later, a move that allowed him to take part in the team's walk thru practices each night, but still kept him from the team's daily contact-workouts.

He returned to the field in time for the 14th practice of training camp. But Thomas was forced to wear a red jersey, the same kind the quarterbacks wear to signal a player that is off-limits to contact.

On Tuesday at Renton's Virginia Mason Athletic Center, as the team rolled its "Competition Wednesday" and "Turnover Thursday" practices into one workout ahead of Thursday's exhibition finale against the Oakland Raiders, Thomas was without that red jersey, participating in his first full practice of the year.

"This is really his first full [practice]," Carroll said. "You could see there was no red shirt on him today."

The All-Pro free safety won't see action this week against the Silver and Black, but Carroll said Thomas should be "ready to go" for the team's regular season opener on Sept. 13 against the Rams in St. Louis.

"He's ready to go, so he'll come back next week," said Carroll. "He'll have to play without the [preseason] game behind him. But he's worked so hard. He looks really fast. He's running great and moving well. I think he's going to be ready to go, as ready as we can get him at this point."

Cornerbacks Richard Sherman, Will Blackmon, and Tharold Simon each saw their first snaps of preseason this past Saturday against the Chargers in San Diego. Thomas' expected return will add another familiar face to a Seattle secondary that was without 11 players during the second week of preseason play.
