Cook (hamstring) was limited to rehab work at Friday's practice, Andrew Krammer of the Minneapolis Star Tribune reports.
It's unclear if Cook will be listed as a non-participant or a limited participant, but he's expected to get a "questionable" designation either way, with his status for Sunday's game against the Eagles potentially coming down to a game-time decision. Another update will be available later Friday when the Vikings release their final injury report of the week.
