Jones knee sprain sidelines him for this week but Shanahan expects a quick recovery and Week 1 readiness; fantasy managers should monitor practice reports for clarity on backup plans and quarterback depth for SF.

Mac Jones appears as part of SF’s QB depth, adding a veteran perspective behind Purdy. While not an immediate fantasy centerpiece, his presence shapes the room’s tempo and could influence development and in-situ decisions if called upon.

Jones contributed 74 passing yards on 4-of-7 while throwing a pick in limited action. With Purdy as SF’s QB1, Jones’s evening underscored the depth challenge at QB behind Purdy and suggested he isn’t pushing for Week 1 reps, making him a speculative hold in deeper leagues only if plans change dramatically.

Jones opened SF’s opener and anchored early drives, representing the primary path to SF’s 2025 QB depth chart. His established NFL floor and veteran presence create a high bar for Mordecai to clear; the presence of a seasoned player in Jones shapes the competition’s tone and the roster calculus for fantasy.

Jones stepped into SF’s rhythm, delivering confident drops and a pocket-preserving approach. His quick timing and ability to read edge pressure enabled an opening-series connection and a sustained drive, though a late misthrow and pressured sequences kept the performance from being flawless. The performance solidified Jones as a focal point in SF’s Week 1 discussions, with expectations tempered by the need to clean up the protection and decision-making.
