Vikings linebacker Chad Greenway has practiced every day this week, but is still considered questionable to return for the Vikings against the Buffalo Bills this week.
Greenway, who had started 90 consecutive games, has missed the last three because of broken ribs and a broken wrist, according to the Star Tribune.
Wednesday he returned to practice for the first time and was a full participant on Thursday and Friday.
"It's going to be a deal where they continue to evaluate [Greenway]," Vikings offensive coordinator Norv Turner told reporters Friday. "It'll probably be a decision made Sunday morning."
Other injuries of note, Sharrif Floyd (elbow) is also considered questionable. He was a limited participant in practice on Friday after missing practice on Thursday. If Floyd is unable to go, Tom Johnson and Shamar Stephen could see more time against Buffalo.
That could mean an opportunity for third-round pick Scott Crichton. Minnesota selected him with their third selection in May's NFL Draft, 72nd overall out of Oregon State. He has only played sparingly and has been a healthy-scratch in most of the games this year.
"They haven't told me anything yet, but I know Corey is out so I'm just getting ready," Crichton said on Friday.
1500 ESPN's Andrew Krammer notes while Crichton said he hasn't been told, he has been working with the first-team field goal unit in practice this week. Crichton worked primarily at right end throughout training camp, but has been playing both end spots this week.
