Miami Dolphins head coach Jeff Hafley confirmed that rookie running back De’Von Achane suffered a knee injury that could keep him out for a significant stretch. Achane entered the 2026 season as a regular starter in most fantasy leagues, so his absence creates a pressing need for owners to find a replacement on the waiver wire for Week 4.

Miami’s Immediate Options

The Dolphins’ depth chart now lists Jaylen Wright as the backup, but he missed Week 3 with a foot injury and entered Week 4 doubtful after missing practice. In his place, Ollie Gordon II stepped into the starting role and finished the Chiefs game with 17 carries for 41 yards, a touchdown, and three receptions for 14 yards. Gordon’s production was modest, but he is healthy and likely to see a larger share of the workload while the team evaluates Wright’s status.

Given the limited upside from both backs, fantasy owners may want to consider looking beyond Miami for a more reliable Week 4 option.

Potential Waiver Wire Additions

Braelon Allen – New York Jets
If Jets starter Breece Hall remains sidelined after his thigh injury, Allen is expected to take over the starting duties over Isaiah Davis. Hall’s status will be clarified on Monday, and a Hall absence would make Allen the most popular waiver‑wire target this week.

Keaton Mitchell – Los Angeles Chargers
Chargers rookie Keaton Mitchell outperformed starter Omarion Hampton in Week 3, posting 52 rushing yards on eight carries and three receptions, including a touchdown. While Hampton still leads the depth chart, Mitchell’s efficiency and involvement in the passing game make him an intriguing upside play.

Justice Hill – Baltimore Ravens
Hill is unlikely to supplant Derrick Henry as the Ravens’ primary back, but the team is a double‑digit favorite against the Tennessee Titans in Week 4. If the game turns into a blowout, Hill could see valuable garbage‑time carries, offering a low‑cost lottery ticket for deeper leagues.

DeeJay Dallas – Minnesota Vikings
The Vikings host the Dolphins in Week 4 and are 9.5‑point favorites. While Aaron Jones will dominate the workload, Dallas could benefit from late‑game garbage time, making him another speculative add for managers seeking depth.

How to Prioritize Your Picks

When deciding which player to claim, consider the following factors:

• Health status – Gordon and Mitchell are confirmed healthy, while Wright and Hall remain questionable.
• Projected workload – Players who are likely to become starters (Allen if Hall is out) provide the most upside.
• Game script – Teams projected to win by large margins (Ravens, Vikings) may offer garbage‑time opportunities for backups.
• Roster construction – If you need a high‑floor starter, Allen is the best bet. For a low‑cost upside play, Mitchell or Hill could fit well.

Final Recommendation

For most fantasy owners, the safest Week 4 move is to target Braelon Allen if the Jets confirm Breece Hall’s continued absence. If you prefer a player already seeing touches, Ollie Gordon II offers a solid, healthy option within the Dolphins’ own roster. For speculative upside, keep an eye on Keaton Mitchell and Justice Hill as potential late‑week contributors.

Stay tuned for the latest injury updates on Wright and Hall, and adjust your waiver claims accordingly before the Week 4 deadline.
