RENTON, Wash. (AP) — The Seattle Seahawks have activated safety Earl Thomas to the 53-man roster, making him eligible to play in Sunday's opener against Denver.

Cornerback Dontae Johnson was placed on injured reserve Saturday after hurting his groin during practice this week. Johnson was expected to start at right cornerback, but rookie Tre Flowers, a converted safety, might now do so. Veteran Neiko Thorpe is another option.

The move with Thomas was expected. He made it through his first week of practice with no issues after holding out of training camp while seeking an extension or a trade. His deal expires after the 2018 season.

Seattle added cornerback Akeem King from the practice squad and waived cornerback Simeon Thomas, who was claimed off waivers this week.
