Marshawn Lynch will be a game-time decision on Monday after “findings” on injured hamstring

The Seattle Seahawks learned of unspecified “findings” from a recent magnetic resonance imaging exam on Marshawn Lynch’s injured hamstring.

That has the five-time Pro Bowl running back’s status as officially questionable and a game-time decision to play against the winless Detroit Lions on Monday night at CenturyLink Field.

“We checked it out and there were some findings,” Seattle coach Pete Carroll said of last week’s MRI.

Carroll did not elaborate on what those findings were following Saturday’s practice. It was the fourth consecutive practice that Lynch missed, dating to the Friday before the win over Chicago last weekend.

“So he’s been working hard at trying to get back,” Carroll said. “He’s done a really diligent job of rehab, and so we’ll see what happens.”

Lynch was also questionable entering the Bears game with what was listed as a calf injury. He missed the first 12 minutes against Chicago, ran five times for 14 yards, then injured his hamstring while bobbling and catching a fourth-down pass and running 9 yards for a first down in the final minute of first half. He didn’t play after halftime.

The 29-year-old foundation to Seattle’s offense has missed one game in his six seasons with the team, when back spasms kept him out of a 6-3 loss at Cleveland in October 2011.

Monday’s game, with rookie Thomas Rawls coming off a 104-yard performance in Lynch’s place, would seem like a grand time to rest Lynch’s leg.

Fred Jackson said the fact there’s doubt about Lynch playing means the injury must be “severe.” If Lynch can’t play against Detroit, Jackson, signed in August, could get his first extended snaps for Seattle as a first- or second-down back spelling Rawls.

“We would go with him if he can make it,” Carroll said of Lynch. “If he can pop out of it, then we would go with him — just based on that he’s had other weeks when he wasn’t able to practice and played very well. But we’ll have to wait and see.”

Carroll said nose tackle Brandon Mebane also will be a game-time decision. Mebane injured his groin during the first half against Chicago.

Reserve linebacker and special-teams player Kevin Pierre-Louis is questionable with a hamstring injury. Carroll said defensive lineman Demarcus Dobbs won’t play because of his injured shoulder.

Dobbs’ absence and Mebane’s iffy status means usual fullback Will Tukuafu will also play on the defensive line Monday, Carroll said. Tukuafu’s versatility to play fullback, tight end and defensive tackle or end led Seattle to keep him on the roster.
