Seahawks middle linebacker Bobby Wagner practiced fully on Friday for the first time this week and will start against Dallas on Sunday in a make-or-break game for the team’s playoff hopes. “He’s ready to go,” coach Pete Carroll said following Friday’s practice. “He practiced today. He’s ready to go.” Wagner also started last week in a 42-7 loss to the Rams but did not practice prior to the game and was taken out in the third quarter. Carroll said Wagner looks better at this point this week than he did last week. “He couldn’t do anything last week,” Carroll said. “We didn’t see him until Sunday. So he’s well ahead of that and that’s a great sign. Because he was able to play last week and we took him out when we had to (once the score was 40-0) he came out of the game better than he was the week before, so the whole week turned out very positive for him.” Also ready to go is weakside linebacker K.J. Wright, who sat out last week with a concussion.
