SEATTLE — The Seattle Seahawks took two steps to sure up their injured-depleted wide receivers by trading for Keary Colbert and reacquiring Koren Robinson today.

Seattle agreed to a one-year contract with Robinson, its former No. 1 draft choice, this afternoon. Agent Alvin Keels confirmed the agreement and its length in an e-mail to The Associated Press.

Colbert was acquired from the Denver Broncos.

Colbert's agent, Gary Uberstine, said this afternoon in an e-mail to The AP his client is also coming to Seattle. Fox Sports.com first reported the trade.

Seattle has lost six players to injury at that position already this season, meaning Robinson and Colbert could play Sunday against St. Louis in a matchup of 0-2 teams.

Robinson could start relatively soon. The free agent, who played for Green Bay last season, started 52 games for Seattle from 2001-04. Coach Mike Holmgren values Robinson because he already knows his offense — unlike some of the players Seattle has recently tried at the position.

Last week, while signing free agents Billy McMullen and the since-waived Samie Parker, Holmgren said he'd welcome back Robinson after his past troubles with alcohol led to his release from the Seahawks in 2005. But team executives apparently nixed that idea — until their situation at wide receiver became even more desperate.

Logan Payne started Sunday's loss to San Francisco but injured a knee. He is the third wide receiver to be out for the season. Backup quarterback Seneca Wallace, pressing into receiver duty, pulled his calf and will miss up to a month.
