Following Sunday's walk-thru, the Seahawks made a couple of changes to their injury report, ruling running back Marshawn Lynch and defensive tackle Brandon Mebane out for Monday's game against the Detroit Lions.

Additionally, linebacker Bruce Irvin was added to the report with an ankle injury, and is questionable for Monday.

Both Lynch (hamstring) and Mebane (groin) had been listed as previously been listed as questionable, and Seahawks coach Pete Carroll said Saturday their statuses might come down to a game-day decision. Instead that decision was made a day earlier, meaning Lynch will miss his first game since being a late scratch for a 2011 game at Cleveland because of back spasms.

Rookie Thomas Rawls, who rushed for 104 yards on 16 carries, will likely carry the load in Lynch's absence along with veteran Fred Jackson. Carroll also said that fullback Derrick Coleman, who played running back in college, could be used as a ball-carrier if needed.

Asked about Rawls on Saturday, Carroll said, "Hopefully we get him in a good rhythm and let him get going again. He was rumbling pretty good last week, and if we're fortunate enough to see that kind of activity again this week we'll be in good shape with him." 

With Mebane out, Jordan Hill will likely take over a starting role, and Carroll said David King, who was inactive for each of the first three game, will play Monday. With Demarcus Dobbs also unlikely to play because of a shoulder injury, the Seahawks will also use fullback Will Tukuafu on defense to bolster line depth, Carroll said.

If Irvin can't play, the Seahawks could either use Mike Morgan to replace him at strongside linebacker, or move K.J. Wright from weakside to strongside, with Kevin Pierre-Louis playing weakside linebacker. The latter option may not be available, however, as Pierre-Louis is questionable as well with a hamstring injury.
