Seahawks’ Thomas may sit vs. Cowboys

Seahawks free safety Earl Thomas was at practice Friday but did not take part because of reasons of a personal nature, according to coach Pete Carroll.

Carroll left open the possibility the issue — he wouldn’t detail — could keep Thomas from playing today in the team’s home opener against the Dallas Cowboys.

“He couldn’t work today,” Carroll said. “... We’ll see how he’s doing. Make sure he’s OK.”

Thomas did not take part in practice on Wednesday either and was listed on the team’s injury report as being out for non-injury reasons. He returned to practice on Thursday before missing the team’s final practice of the week on Friday.

Carroll confirmed that his absence had nothing to do with an injury.

“He’s got some other stuff going on we’re working on,” Carroll said.

Thomas held out from all offseason work with the Seahawks in hopes of getting a new contract from the Seahawks. The move did not succeed despite Thomas’ efforts and he reported to the team before the start of the regular season.

Steelers: Will be without All-Pro guard David DeCastro for a second straight week when they visit Tampa Bay on Monday night. DeCastro is still recovering from a fractured right hand suffered in Week 1. B.J. Finney will start in DeCastro’s place.

Right tackle Marcus Gilbert is doubtful with a hamstring issue. The Steelers expect veteran cornerback Joe Haden to return after missing last week’s loss to Kansas City with a hamstring problem.
