Dalvin Cook Injury Update

Cook suffered a dislocated shoulder on Sunday, opening the door for Alexander Mattison to have an expanded role. However, it looks like Cook could return soon. The talented back has a history of shoulder dislocations as well as an unrepaired labral tear. He will likely wear a harness in future games and should be healthy enough to play on Sunday morning in London. Unless Cook re-injures the shoulder, his existing injury and the presence of the harness shouldn’t hurt his fantasy value too much. He still falls into the mid-RB1 range against the Saints, assuming he is active.

D’Andre Swift Injury Update

Swift suffered a shoulder sprain in Week 3 that put him in a secondary role behind Jamaal Williams. Head coach Dan Campbell said on Tuesday that Swift could benefit by skipping the next two games to let his shoulder heal, then return after the Lions’ bye week. Although it remains to be seen whether Campbell follows through on this plan, fantasy managers should prepare to be without Swift for nearly a month. In his absence, Williams will see more involvement as a runner and receiver, ranking as a mid-range WR2.

Joe Mixon Injury Update

Mixon (ankle) was limited in practice on Monday, then upgraded to a full participant on Tuesday. Unless he suffers a setback, it looks like he should play on a short turnaround this coming Thursday. Still, fantasy managers invested in Mixon’s availability might consider adding Mixon’s backup, Samaje Perine, if they have vacant bench or IR spots.
