Apple elevated from the 49ers’ practice squad ahead of Week 4 versus Jacksonville, giving San Francisco veteran depth at cornerback behind Renardo Green, who is dealing with a neck issue and listed questionable. Green played 86% of snaps last week but was limited in practice. The WR group isn’t being boosted with an elevation, as Demarcus Robinson and Jauan Jennings are the primary targets with Pearsall likely to play if limited.

Keith the depth chart: Deommodore Lenoir, Darrell Luter Jr., Chase Lucas and Upton Stout provide cover in the secondary, while Pearsall, Jennings, Robinson, Skyy Moore and Marques Valdez-Scantling headline the Week 4 receiving corps. Levi’s Stadium hosts the 1:05 p.m. kickoff against the Jaguars.

Week 4 looks stabilized at quarterback for the 49ers as Brock Purdy nears a return from a toe injury, reducing major fantasy risk at the position. Mac Jones remains a questionable backup, but Purdy’s health is the backbone for San Francisco’s Week 4 upside.

In the receiving corps, Jennings and Pearsall carry injury risk. If both sit, Demarcus Robinson and Kendrick Bourne would step into lead roles, giving fantasy managers a late-week option with Robinson’s season debut on deck. Other listed veterans and depth pieces (Watkins, Green, West, Colby, Davis) create depth concerns more than fantasy pivots unless top WRs are sidelined.

Week 4 looming against Jacksonville keeps an eye on injuries as the key differentiator for lineups. Stay tuned to the final injury report and readiness news to gauge start/sit decisions for the 49ers’ pass game and potential DFS value.
