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.
