The Seahawks Saturday released wide receiver/kick returner Bryan Walters and signed safety Terrance Parks from the practice squad to the 53-man roster. The move adds some depth to Seattle’s injury-riddled secondary in advance of Sunday’s 1:25 p.m. game against the Oakland Raiders at CenturyLink Field.

The 24-year-old Parks signed with the Seahawks in February after spending time with the Kansas City Chiefs and the Canadian Football League’s Hamilton Tiger-Cats following a college career at Florida State. The 6-foot-2, 218-pounder could see action Sunday with starter Kam Chancellor a game-time decision with a groin injury and reserve Jeron Johnson out with a concussion.

Parks has never played in an NFL game.

A Kirkland native, Walters signed with the Seahawks’ practice squad in 2012 after playing four games with the San Diego Chargers during his 2011 rookie season. The 26-year-old saw action in six games for the Seahawks this season, serving as the primary punt returner from Week 2 through Week 7.

Walters did not play in last week’s victory at Carolina after a concussion at practice.

The fourth-year player from Cornell averaged 9.1 yards per return on 12 punts and 21.5 yards per return on two kickoffs to go with five receptions for 44 yards.
