This is the team's release:
The Seattle Seahawks have placed guard Mike Wahle on injured reserve and signed center Steve McKinney to the active roster, the team announced this morning. Wahle is the third starting offensive lineman to land on injured reserve this season, and sixth opening day starter to land on the list. The team also signed defensive tackle Kevin Brown to the practice squad.
Wahle, signed this past offseason, started all 10 games played this season before suffering a shoulder injury vs. Arizona (11/16).
McKinney comes to Seattle after spending four years in Indianapolis (1998-2001), six years in Houston (2002-07) and training camp with Miami this year. He has played in 143 games with 133 starts at both center and guard. He was originally a fourth-round draft choice (93rd overall) by Indianapolis in the 1998 NFL Draft.
