Diggs sustained an injury to his ribs in the second quarter of a 30-20 loss to the New Orleans Saints after catching a 19-yard screen pass and hitting the ground after he was tackled. The wide receiver did not practice Wednesday, Thursday or Friday.
Cook also practiced in limited capacity this week after shutting down football activity entirely in the days leading into the game against the Saints. The running back is recovering from a hamstring injury he sustained in Week 2 and said he won't fully know how his body will respond until he gets in a game.
"I've been practicing all week," Cook said Thursday. "I'm in a comfortable spot. I just got to keep stacking the days up. One thing about injuries -- you can't ever replicate a game in practice. Tweaking and turning your body and getting tackled. We don't tackle in practice. So you'll never know."
Cook's participation in practice Friday gives the Vikings hope that he will be able to play against the Lions. Sources indicated that Cook will go through an on-field workout prior to inactives before determining whether he can play. He went through a similar process before the Week 6 game against the Arizona Cardinals. If Cook is good to go, he'll be on a limited pitch count, which is expected to be around 15 to 20 plays, according to a source.
"If guys can play, they'll play," coach Mike Zimmer said. "That's just how we do it around here. We're not going to worry about six weeks down the road or anything like that."
