Redskins RB Adrian Peterson will start Sunday's opener against the Cardinals, ESPN's John Keim reports. It's unclear how many carries RB Rob Kelley will get, and RB Chris Thompson will dominate passing-down work. Peterson sits 30th in our Week 1 non-PPR RB Rankings and 37th in PPR.

Seahawks RB Adrian Peterson will not play against the Texans on Sunday due to a lower-back injury, HC Pete Carroll said. Peterson never appeared on this week's injury report because he's on the practice squad. With RB Travis Homer out, Seattle is down to RBs Rashaad Penny, Alex Collins and DeeJay Dallas. Carroll said Penny will be a "big part" of the game plan this week. He looks like the best fantasy bet here, but this is still a backfield to try to avoid.

NFL Network's Ian Rapoport hears that Seahawks RB Adrian Peterson is expected to get the "bulk of the carries" vs. the 49ers today. Peterson just joined the team on Wednesday but "looked great in practice," per Rapoport. Peterson, of course, flopped in Tennessee, and we're not optimistic about his production in this struggling Seattle running game. Avoid the Seahawks backfield in Week 13 fantasy lineups.

ESPN's Jeremy Fowler reports that the Seahawks will be activating RB Adrian Peterson ahead of Sunday's game against the 49ers. That indicates the veteran will be playing less than a week after joining Seattle's practice squad. Peterson, of course, already washed out with a needy Titans backfield this season and now joins a running game that has struggled in general. Adding a member to this lackluster committee only makes the whole situation more of an avoid for fantasy lineups.

The Seahawks are signing RB Adrian Peterson to their practice squad. Here we go again. Peterson was completely ineffective in 3 games for the Titans earlier this season, averaging 3.0 yards per carry. Now he joins a Seattle running game that's been close to useless all season. We'll see if Peterson gets promoted to the active roster, but we wouldn't bother adding him in fantasy outside of the deepest of leagues.

The Titans released RB Adrian Peterson. This could be the end of the road for the 36-year-old, who averaged just 3.0 yards on 27 attempts over the past 3 weeks. Tennessee will move forward with RBs D'Onta Foreman, Dontrelle Hilliard and Jeremy McNichols for as long as Derrick Henry is out.
