That didn't take long.
The Seahawks saw enough Sunday in Kansas City when the Chiefs steamrolled them for 190 yards rushing and they went nowhere on offense after center Max Unger got hurt. Less than 48 hours after that they brought back Lemuel Jeanpierre from an injury settlement to replace Unger. And they signed 304-pound Travian Robertson off the Atlanta Falcons' practice squad onto the active roster to try to help fill the huge void of Brandon Mebane being injured at nose tackle.
Jeanpierre sustained a neck injury at the end of the exhibition season. Seattle placed him on injured reserve Sept. 3. On Sept. 10 he received an injury settlement from the Seahawks, making him a free agent able to sign elsewhere and potentially play again this season. He had a couple NFL tryouts but remained unsigned -- until after Unger sustained a high-ankle sprain with 9 minutes to go in Sunday's 24-20 loss at Kansas City.
The Seahawks’ offense that had 550 yards rushing for the two games Unger had been back in the middle of the line following a sprained foot last month suddenly stalled Sunday when he got hurt with Seattle inside the Chiefs’ 10, poised for the go-ahead score. Fourth-string center Patrick Lewis, signed and released early this season and re-signed recently, finished the game.
The Seahawks had 20 points and were averaging 6.2 yards per play, including 5.8 yards per rush, with Unger in. They had zero points, 1.8 yards per play and 1.3 yards per run after he got hurt.
Coach Pete Carroll said on Monday he expected Unger to miss at least three or four of Seattle's final six regular-season games.
So the Seahawks (6-4) weren't exactly comfortable with Lewis starting the must-win game Sunday against the soaring Arizona Cardinals (9-1) and their rampaging defense at CenturyLink Field.
Jeanpierre, the 27-year-old, former undrafted free agent, has played in 47 games with eight starts as Unger's backup the last three seasons. He has played in five postseason games for Seattle.
The beauty of bringing back Jeanpierre is he conceivably could start on Sunday against Arizona, pending how much football shape he is in right now or can get in by this weekend. He knows the blocking system and calls of Seahawks line coach Tom Cable better than Lewis does.
Robertson is 6 feet 4, 304 pounds and plays nose tackle — the spot where Brandon Mebane was starring until he tore his hamstring two games ago. In their first game without Mebane stuffing blocks over the center, the Seahawks’ top-ranked run defense allowed Kansas City to romp for 190 yards on the ground. ESPN.com’s Terry Blount broke down those runs and found 118 of the Chiefs’ 190 yards rushing came between the tackles, right at fill-in nose tackles Kevin Williams and Jordan Hill — right through where Mebane had been putting up brick walls.
Robertson hasn’t played this season but played in 12 games over the previous two seasons for Atlanta. He was the Falcons' seventh-round draft choice in 2012 out of South Carolina.
To make roster room the Seahawks released safety Steven Terrell, who played in four games mostly on special teams this season, and never used offensive tackle Andrew McDonald.
--By popular demand (pabuwal, don't say I never do anything for you!), below are the snaps counts from Kansas City.
Note Kam Chancellor played every defensive snap with bone spurs in both ankles, his first game back after missing two games with a groin injury.
Malcolm Smith also played for the first time in three weeks following a groin injury, and played 45 of 48 snaps -- because he had to with linebackers Bobby Wagner and Brock Coyle out.
Will Tukuafu got the first three-column entry this season -- offense, defense and special teams. He may do it again this weekend.
You'll see Christine Michael barely got in on offense, just when it looked like his 70-plus-yard rushing day against the Giants the week before might have elevated him to the No. 2 running back ahead of Robert Turbin, who fumbled that day. Michael was very agitated two different times when he came off the field after his plays on offense, waving his arms gesturing angrily. What appeared to me to be one of the offensive quality-control coaches (hard to tell from across the field, top of Arrowhead Stadium through binoculars, but it wasn't a position coach or OC Darrell Bevell) was angrily gesturing and pointedly talking back to Michael.
