Three weeks of real data are now in, and several Fantasy Football Week 4 Sleepers have emerged from pure matchup luck, injury-created opportunity, or simply being overlooked by drafters back in August. These seven names all carry genuine weekly upside well below their current roster rates. None of them should cost much to add off your waiver wire this week, and a couple could even be sitting unclaimed in shallower league formats.
Fantasy Football Week 4 Sleepers: Deshaun Watson, QB, Cleveland Browns
Deshaun Watson has quietly been a top-10 fantasy quarterback through three weeks, currently sitting at QB10 overall. Despite that production, he remains rostered in just 7% of Yahoo leagues league-wide. He’s contributing on the ground as well as through the air. That dual-threat profile gives him a higher weekly floor than his modest ownership number would otherwise suggest.

Fantasy Football Week 4 Sleepers: Jacoby Brissett, QB, Arizona Cardinals
Jacoby Brissett finished as last week’s QB4, throwing for 280 yards and two touchdowns against the San Francisco 49ers. The Arizona Cardinals fell behind early in that game and had to pass more often than originally planned. He’s rostered in only 11% of leagues, making him a genuinely cheap streaming option for anyone needing a one-week spot start.
Fantasy Football Week 4 Sleepers: Tyler Higbee, TE, Los Angeles Rams
Tyler Higbee stepped into a featured role after Terrance Ferguson’s ankle injury forced him out during Week 3. Higbee caught eight of 11 targets for 62 yards and a touchdown that afternoon. He also ran a route on 77% of the Los Angeles Rams’ passing plays once Ferguson left the game. With Ferguson’s status still uncertain, Higbee could stay fantasy relevant again this week.
Fantasy Football Week 4 Sleepers: Roman Wilson, WR
Roman Wilson has seen at least six targets in every single game he’s played so far this season. He’s also coming off his best outing yet, totaling 60 receiving yards and 15 PPR points in Week 3. He leads all qualifying receivers in target-per-route-run rate, sitting at an impressive 23%. This week’s opponent, the Cleveland Browns, have allowed the sixth-most fantasy points to receivers. Wilson took advantage last night with three receptions for 74 yards and a touchdown. He ended up with 16 fantasy points, maintaining his quality play.

Fantasy Football Week 4 Sleepers: Keenan Allen, WR, Indianapolis Colts
Keenan Allen rounds out this week’s receiver sleepers after re-establishing himself as a trusted target in Indianapolis. His veteran route-running continues to generate consistent weekly looks from his quarterback. That steady target share gives him a reliable floor in an offense leaning on him more than many expected early this season.
Fantasy Football Week 4 Sleepers: CJ Donaldson, RB, New Orleans Saints
With Travis Etienne expected to miss Week 4, the New Orleans Saints turn to a committee featuring Alvin Kamara, Kendre Miller, and CJ Donaldson. He currently sits third on that depth chart behind both veterans. Still, Donaldson has a real path to extra snaps, after a teammate was recently benched for a costly blown pass-protection assignment.
Fantasy Football Week 4 Sleepers: Brenton Strange, TE, Jacksonville Jaguars
Brenton Strange checks several boxes for a streaming tight end option this week. He handled five targets in last week’s game alone. He’s also already found the end zone once already this season. That combination gives him a reasonable weekly floor in an offense still settling into its passing-game rhythm under center.
Fantasy Football Week 4 Sleepers: Why Low Ownership Matters This Week
Every player on this list shares one trait beyond raw talent: availability. A sub-15% rostered player who posts even a mediocre week still beats a bench spot sitting empty. Streaming quarterbacks like Watson and Brissett are especially valuable in two-quarterback or superflex formats. Their low ownership numbers mean they’re often sitting untouched on your waiver wire right now. Someone just has to notice the underlying numbers behind their recent production.

End Of My Fantasy Football Week 4 Sleepers How To Use These Picks
None of the seven fantasy football Week 4 sleepers should be locked into a competitive lineup without first checking your own roster needs and league scoring format. Watson, Brissett, and Higbee carry the clearest paths to immediate production this week. Wilson, Allen, Donaldson, and Strange lean more toward matchup-based, boom-or-bust plays worth monitoring closely before Sunday’s kickoffs arrive. Adding even two or three of these names costs little in free-agent bidding. One real breakout week from any of them could meaningfully change your fantasy season. That’s especially true in formats where waiver priority resets weekly and the cost of being wrong stays low.
