​The Seattle Seahawks just made a move that could have a major impact on the fantasy football landscape. Zach Charbonnet has been designated to return to practice, opening his 21-day window to potentially return from the physically unable to perform list.The #Seahawks have designated RB Zach Charbonnet to return to practice. pic.twitter.com/aPVyyZJKYP— Ian Rapoport (@RapSheet) October 1, 2026Charbonnet is not expected to play this week, but he now has a chance to return as soon as Week 5 or Week 6. That makes him one of the most intriguing running back stashes in fantasy football, especially for managers looking for a potential difference-maker for the second half of the season.MORE:Fantasy Football studs & duds for Week 4 of 2026 NFL seasonSeattle’s backfield has been difficult to trustDec 7, 2025; Atlanta, Georgia, USA; Seattle Seahawks running back Zach Charbonnet (26) runs the ball against the Atlanta Falcons in the fourth quarter at Mercedes-Benz Stadium.

Rookie Jadarian Price entered the season with significant expectations after Seattle selected him with the final pick of the first round, but his production has been inconsistent.Through three games, Price has 28 carries for 119 yards and no touchdowns, while also recording four receptions for 21 yards. He has also lost two fumbles.Seattle has used multiple backs throughout the season, and Seahawks head coach Mike Macdonald previously indicated that the team planned to feature two or three running backs depending on the week.That uncertainty could change significantly once Charbonnet is ready.MORE:Fantasy Football biggest injuries entering Week 4Charbonnet could become a massive fantasy valueJan 3, 2026; Santa Clara, California, USA;Seattle Seahawks running back Zach Charbonnet (26) rushes for a touchdown against the San Francisco 49ers during the first half at Levi’s Stadium.

He rushed for 730 yards and 12 touchdowns on 184 carries while adding 20 receptions for 144 yards.The biggest question is how quickly Seattle will increase his workload after recovering from his ACL injury. There is no guarantee that he immediately takes over the backfield, but his track record gives him a strong opportunity to eventually become the Seahawks’ primary running back.That makes Charbonnet an extremely appealing fantasy football stash. He was available extremely late in many drafts and could still be sitting on waiver wires in some leagues.If Charbonnet returns healthy and eventually takes control of Seattle’s backfield, an RB2-level role could be within reach.
