The Seattle Seahawks activated safety Steven Terrell from the practice squad and waived defensive end Greg Scruggs on Saturday.

The move is a possible sign that strong safety Kam Chancellor will not be able to play Sunday against the Dallas Cowboys. Chancellor suffered a hip injury last week and was listed as questionable Friday.

On Friday, coach Pete Carroll said of Chancellor, “We’ll run him on game day and see how he feels and see if he can go.”

If Chancellor is out, Jeron Johnson will start at strong safety.

Terrell had spent the season on Seattle’s practice squad. An undrafted free agent in 2013, he was a practice player in Jacksonville and Houston last season.

Scruggs had been inactive all season as the Seahawks’ ninth defensive lineman. The 2012 seventh-round pick missed last season with a torn ACL and had been expected to contribute heavily in 2014. But he had been unable to crack the lineup as veteran Kevin Williams, second-year player Jordan Hill and rookie Cassius Marsh had earned playing time ahead of him.
