Week 5 Fantasy Football FLEX Rankings Outlooks
Demarcus Robinson, San Francisco 49ers
San Francisco 49ers wide receiver Demarcus Robinson is expected to slide into a starting role with Ricky Pearsall (knee) and Jauan Jennings (ankle/ribs) out for Week 5. Robinson made his season debut in Week 4 after serving a three-game suspension for violating the league's substance abuse policy in the offseason.
San Francisco eased Robinson into action with a 25% snap share, and he saw just two targets, catching one pass for 20 yards. Robinson should see more action this week, though his lack of conditioning might see him lose snaps to Skyy Moore or Marquez Valdes-Scantling.
It is worth noting that quarterback Brock Purdy (toe) will also be sidelined, with Mac Jones getting the start. As a projected WR5, it would be inadvisable to plug him into starting fantasy lineups, especially with the 49ers playing on Thursday, in the first game of the week.
Kendrick Bourne, San Francisco 49ers
In Week 5, San Francisco 49ers wide receiver Kendrick Bourne will once again ascend to the top of the depth chart thanks to injuries to both Ricky Pearsall (knee) and Jauan Jennings (ankle/ribs). Bourne started alongside Pearsall in Jennings' absence in Week 3, and came away with four catches and 38 yards on six targets.
Hardly the boom some were hoping for, but with Pearsall also sidelined this time around, Bourne could see more work. As in Week 3, Bourne's former Patriots teammate, quarterback Mac Jones, will take the place of Brock Purdy (toe).
It should be noted that their shared history didn't garner the receiver any special attention then, however. Bourne projects as a WR4 in Week 5, and with the 49ers playing on Thursday night, it is a risky bet to start the week with him occupying a starting WR slot in fantasy lineups.
Calvin Ridley, Tennessee Titans
Tennessee Titans wide receiver Calvin Ridley (knee/elbow) did not practice on Wednesday. Ridley has struggled to start the 2025 season, catching just 10 of 24 targets for 141 yards with no touchdowns, ranking as the WR73 in PPR formats.
Head coach Brian Callahan revealed Ridley was battling through an in-game injury during last week's 26-0 loss to the Houston Texans, raising further concern about his availability.
If Ridley is sidelined in Week 5, rookie Elic Ayomanor is expected to see a significant uptick in usage against the Arizona Cardinals. Regardless of his injury status, Ridley's early-season struggles and difficult circumstances in the Titans offense make him a clear sit in fantasy lineups this week.
Juwan Johnson, New Orleans Saints
New Orleans Saints tight end Juwan Johnson (ankle) did not practice on Wednesday. Johnson is coming off his least productive game of the season in Week 4, catching just three passes for 28 yards. He now appears to be dealing with an ankle injury that he picked up during the loss against the Buffalo Bills, but he managed to play nearly 90% of the snaps.
If Johnson is unable to go in Week 5, Jack Stoll would step in as the Saints' starting tight end. The matchup is not ideal, as the New York Giants have surrendered the 10th-least fantasy points to tight ends this season. If Johnson suits up, he projects as a low-end TE1 option in Week 5, but fantasy managers should keep an eye on his practice participation.
