EAGAN, Minn. — One top Minnesota Vikings offensive player was declared ready to play for Sunday. It remains a waiting game on two others.

Head coach Mike Zimmer said Thursday he expects running back Dalvin Cook to play against Detroit at U.S. Bank Stadium and be close to 100%. Cook, knocked out in the third quarter of Monday’s 37-30 loss at Seattle with a chest injury, was limited in practice Thursday.

Wide receiver Adam Thielen, who has missed three straight games with a hamstring injury, and tackle Riley Reiff, who suffered a concussion in the first half against the Seahawks and didn’t play in the second half, did not practice Thursday. Zimmer said both still have a chance to play against the Lions.

“I think he’s got a good opportunity this week, so we’ll see,’’ Zimmer said of Thielen. “He’s working really hard. He obviously wants to get out there with his guys. … When he’s ready, he’s ready and he’ll get in and play. If he’s not ready, he won’t play.’’

Thielen was limited in practice last Friday and Saturday before being ruled out Sunday for the game at Seattle. Zimmer said he did not have a setback in his recovery.

Thielen, who has missed four of the last five games, was initially hurt Oct. 20 at Detroit. He acknowledged last week he returned too soon from his injury Nov. 3 at Kansas City, a game he left in the first quarter.

“We always get an MRI, sometimes two or three MRIs to see where they’re at,’’ Zimmer said of players with hamstring injuries. “If the MRI looks pretty good, you trust the player. If the player says he can play, then you let him play, and that’s kind of what happened (at Kansas City).

“We’ve gotten a couple more MRIs (on Thielen). I think he’s getting really close. There’s really no sense to push it like (Thursday.) … We’ll see how it goes next week or (Friday).’’

If Thielen can’t play against the Lions, he again would be replaced by rookie Bisi Johnson.

“When one guy is down, one steps up,’’ Johnson said.

While all Minnesota players this season who have suffered a concussion have sat out the following game, Zimmer said there remains hope Reiff can play against his former team.

“He’s in the (concussion) protocol right now, so he’s got to take a test (Thursday),’’ Zimmer said. “We’ll see.’’

If Reiff can’t play, he would be replaced by Rashod Hill. Hill declined comment Thursday.

Also limited in practice Thursday were defensive end Everson Griffen (knee) and defensive tackles Linval Joseph (knee) and Shamar Stephen (knee).

The Vikings on Monday placed linebacker Ben Gedeon on injured reserve with a concussion suffered Nov. 17 against Denver, ending his season. Zimmer on Thursday commented for the first time on the move.

“Ben loves to play, and I think maybe he might have pushed it a little too far,’’ Zimmer said. “He should have just been a little more patient with (the injury). He passed all the tests, but sometimes it reoccurs on certain things, and it was bothering him for a while.’’
