Cornerback Danny Gorrer has been signed to Seattle's 53-man roster, running back Kregg Lumpkin released to make room for him.

Lumpkin was signed by Seattle this offseason after playing the last two seasons with Tampa Bay. The Seahawks had tried to claim Lumpkin in 2010, placing a waiver claim on him from the Packers. Lumpkin was the fourth running back on the roster behind starter Marshawn Lynch, rookie Robert Turbin and Leon Washington. Lumpkin -- who could also play some fullback -- was inactive for the first two games.

Gorrer played at Texas A&M and entered the NFL as an undrafted rookie. He was on the Ravens' practice squad in 2010 and played 14 games for the Ravens last year.

His addition comes after second-year cornerback Byron Maxwell suffered a hamstring injury in the first half of Sunday's game vs. Dallas. Maxwell has been a special-teams player so far in his time with the Seahawks.

Seattle also re-signed G Rishaw Johnson and LB Korey Toomer to the practice squad, releasing WR Ricardo Lockette and LB Allen Bradford to make room for them.
