The Seattle Seahawks have given general manager John Schneider an extension through 2016.

The Seahawks have kept the extension quiet as it has been done for over a year.

Pete Carroll is signed through the 2014 season.

Tarvaris Jackson is expected to sign a one-year deal with the Seattle Seahawks.

Jackson was released by the Buffalo Bills this week.

Jackson played for the Seahawks in 2011, starting 14 games, completing 60.2 percent of his passes for 3,091 yards and 14 touchdowns (to 13 interceptions).

The Seahawks traded Matt Flynn to the Oakland Raiders this offseason.

Jim Harbaugh spoke on Tuesday about the inordinate number of performance enhancing drug suspensions that have hit the Seattle Seahawks.

"I've definitely noticed it," Harbaugh said in comments distributed by the San Francisco 49ers. "You don't know what it is. Even when people say what it is, you don't know that that's what it is. For this, throw it out, or it's that. But, that's usually the agents of the players themselves saying it's, for example Adderall.

"But, the NFL doesn't release what it actually is. So, you have no idea. You're taking somebody at their word, that I don't know that you can take them at their word, understanding the circumstances."

Pete Carroll looked to downplay the story when reached to reply.

"We've kind of dealt with this to set into motion a really clear mindset to take care of business and treat this situation that is around the league very seriously. I don't know about commenting about anybody else's team, but as far as we're concerned we feel like we've addressed it directly," Carroll said via the Associated Press.
