Friday's practice report tells us the Seahawks will be without at least four players to injury in Sunday's game against the Vikings at Minnesota's TCF Bank Stadium: running back Marshawn Lynch (abdomen), wide receiver Paul Richardson (hamstring), defensive end Demarcus Dobbs (concussion), and defensive tackle Jordan Hill (toe).

It will be the third consecutive game Richardson has missed after the setback he suffered in Week 10 against the Arizona Cardinals, his first game back after starting the season on the team's physically unable to perform list. Seattle head coach Pete Carroll said it doesn't look like Richardson will be able to return next week, either, and offered a "we'll wait and see" when asked if a roster move would be made for Richardson's place on the 53-man roster.

"His hamstring just isn't coming back," Carroll said Friday before the team left for Minneapolis. "And so we're just disappointed that he wasn't able to continue to get back. It just lingered a little bit.

"In working him out and trying to get him back he could still feel it," Carroll added. "So it just hasn't gone away yet like we had hoped."

Dobbs and Hill failed to make it back from the injuries they suffered in this past Sunday's win over the Pittsburgh Steelers, while Lynch remains out after undergoing surgery late last month.

"It's going to call for A.J. Francis to play for us," Carroll said of the 6-foot-5, 321-pound former Uber driver who was promoted from the practice squad earlier this week with the injuries to Dobbs and Hill in mind. "That's important. We're dissapointed to lose those guys. Other guys have to roll in to fill the spot.

"We haven't seen a lot of him in the physical side of things, other than the film we've watched," Carroll added of what Francis will bring. "He plays big, we think he's going to hold the point real well, and that's what we're hoping he'll get done for us, be physical at the line of scrimmage."

Questionable for the Seahawks are fullback Will Tukuafu (concussion) and cornerback Marcus Burley (ankle), each of whom were hurt in the team's Week 12 win over Pittsburgh. Both players were limited at Friday's practice. 

"He's just coming back from an ankle that we think he's going to make it," Carroll said of Burley. "We have him listed as questionable right now, but we think he can pull it off."

For the Vikings, starting nose tackle Linval Joseph (foot) has been ruled out after not practicing all week, as has starting strong safety Andrew Sendejo. Starting strong-side linebacker Anthony Barr, who had eight tackles, a sack, one pass defensed, and two forced fumbles in Minnesota's Week 12 win over the Atlanta Falcons, was a limited participant in Friday's practice after sitting out on Thursday and is listed as questionable for Sunday's game. Harrison Smith is questionable as well, but the team's starting free safety worked in limited fashion all week.
