Overview
- Mac Jones is set to start Thursday night at the Rams, with Adrian Martinez elevated to serve as the backup quarterback.
- San Francisco used standard elevations on defensive lineman Trevis Gipson and wide receiver Malik Turner for game day.
- The team waived defensive lineman Jordan Jefferson to open a roster spot and re-signed cornerback Derrick Canteen to the practice squad.
- Receivers Ricky Pearsall (knee) and Jauan Jennings (ankle, rib) were ruled out, with Turner adding depth to a thin position group.
- Martinez has no NFL regular-season snaps and joined the 49ers’ practice squad on Aug. 28 after a Jets stint, a full promotion that some outlets view as a sign Purdy’s status could remain uncertain.
