Vikings RB Dalvin Cook (shoulder) is out for Sunday’s game vs. the Lions. It sounds like a Week 15 return is his best-case scenario. RB Alexander Mattison is a good bet for 20+ touches against Detroit’s 29th-ranked RB defense, making him an elite fantasy play.

Dalvin Cook is expected to open the season as the Jets' lead back, per NFL Network's Ian Rapoport. "Dalvin Cook is expected to get the bulk of the carries for the New York Jets at least during the early part of the season," Rapoport adds. "My understanding is that they'll be extremely smart and safe with" RB Breece Hall. No surprises here. Cook figures to be the more reliable fantasy option early in the season. But Hall's touches should climb throughout the year.

Jets RB Dalvin Cook is a "full go" for Monday night's opener vs. the Bills, ESPN's Jeremy Fowler reports. "He's fully recovered from offseason shoulder surgery, and the early returns from last week's first practices were positive," Fowler adds. Cook is a full go from a health standpoint, but it's still unclear how big a role he'll be ready for on Monday after signing with the Jets on August 14 and practicing with the team for the first time on August 29. Cook is just a RB3 or flex option in Week 1 fantasy lineups.

RB Dalvin Cook practiced with the Jets for the first time on Tuesday. He signed a little over two weeks ago but still needed to be medically cleared from offseason shoulder surgery and was away for the birth of his first child. ESPN's Adam Schefter confirms that Cook is expected to play in the season opener vs. the Bills. How snaps are split between Cook and RB Breece Hall is one of the biggest fantasy questions of Week 1.

ESPN's Adam Schefter reports that new Jets RB Dalvin Cook is still "at least a week away" from being cleared to practice after undergoing shoulder surgery in February. It sounds like Cook should be ready in time for Week 1, but the missed practice time isn't ideal as he works to settle into a new offense. We'll see when he's able to get on the field. Teammate Breece Hall, of course, remains on the PUP list.

The Jets have agreed to a one-year deal with RB Dalvin Cook. NFL Network's Tom Pelissero reports that Cook is getting "up to $8.6 million ... with the majority guaranteed." He adds that it's the largest annual average of any deal for a RB free agent this offseason. This seems to signal a few things: First, the Jets like Cook much better than any of their current RB backups and were iffy enough on that crew to make a significant upgrade. Secondly, it also indicates they want to make sure not to overwork Breece Hall in his return from the ACL tear. Hall has yet to take the field in training camp, though reports have said they expect him to be ready for the regular season. Even if that holds true, expect Cook to cut way into the available work. That moves Hall down our RB rankings and gives Cook nice contingent upside, in case Hall misses further games. The rest of the Jets' current RBs are no more than end-of-draft fliers. At least one among Michael Carter, Zonovan Knight, and Israel Abanikanda probably isn't making the regular-season roster.
