"He's frustrated. I think he's got a good opportunity this week (to play), so we'll see," Zimmer said of Thielen Thursday, via Chris Tomasson of the St. Paul Pioneer Press. "He's working really hard. He obviously wants to get out there with his guys. He's a great competitor. ... When he's ready, he's ready.''
Thielen hasn't been ready since suffering the initial hamstring injury in Week 7, the first time Minnesota played Detroit. The wideout attempted to return in Week 9 but played just six snaps against the Chiefs before sitting out the rest of the contest. He's missed the entirety of the past three games.
Zimmer's optimism is interesting considering Thielen did not participate in practice again Thursday after also sitting out Wednesday's session. The coach noted Thielen has not suffered a setback recently.
Zimmer said he believes the running back will be close to 100 percent for the tilt against the Lions. Cook was limited in practice Thursday.
