The Seahawks announced Saturday they released center Jason Spitz and signed wide receiver Bryan Walters from the practice squad to the 53-man roster.

That makes Walters eligible to play in Sunday’s game against the Titans and gives the Seahawks five receivers for that game. They played with four last week after the release of Stephen Williams.

Walters, from Kirkland’s Juanita High School, originally entered the NFL as an undrafted rookie free agent with the San Diego Chargers in 2010, where he spent the final five games on the Chargers’ practice squad.

He saw action in four games in 2011, recording three receptions for 27 yards and eight punt returns for 45 yards. Walters then signed with the Minnesota Vikings as a free agent on April 2, 2012, but was released during training camp and signed to Seattle’s practice squad on December 20.

Spitz signed with Seattle on Sept. 25 and dressed, but did not play, in two games this season.

Spitz was signed as insurance with Max Unger out. But Unger will be back this week, so the team does not need a third center.

Browns put Hoyer on injured reserve

CLEVELAND — The Browns have placed quarterback Brian Hoyer on injured reserve with a torn knee ligament, officially ending his season.

Hoyer led Cleveland to two wins in his first two starts. He tore the anterior cruciate ligament in the first quarter of Cleveland’s victory over Buffalo on Oct. 3.

Hoyer was sliding at the end of a run when his cleat got caught in the turf as he hit the ground. Hoyer will undergo surgery next Friday.

The Browns waited to put Hoyer on IR as they considered signing another quarterback.

The club instead signed rookie wide receiver Charles Johnson off Green Bay’s practice squad. The Packers drafted him in the seventh round in April. He played in Green Bay’s final two exhibition games.

Cleveland hosts Detroit on Sunday.
