Coach Mike Zimmer reportedly views Cook (ankle) as a game-time decision for Sunday's game against the Lions, according to Adam Schefter of ESPN.
Cook didn't practice either Wednesday or Thursday but returned to a limited session Friday and is officially listed as questionable heading into Sunday's 1:00 ET kickoff. Per Schefter, if Cook does suit up against Detroit, it's not a lock the running back would be slated for his normal workload. In that context, Alexander Mattison -- who logged 10 carries in Cook's return to action last weekend -- would continue to remain a factor in Minnesota's rushing attack in Week 5.
