Overview

• San Francisco waived/injured quarterbacks Carter Bradley and Tanner Mordecai, waived defensive linemen Jaylon Allen and Shakel Brown, released running back Ke'Shawn Vaughn, and placed offensive lineman Isaiah Prince on injured reserve.
• Kyle Shanahan said he expects Jauan Jennings to be ready for Week 1, though multiple reports say the team has considered opening him on injured reserve due to his lingering calf issue and growing frustration over missed practices.
• Rookie wide receiver Jacob Cowing re-injured his hamstring and is expected to be out about six weeks, making him an IR candidate, according to Shanahan.
• Brandon Aiyuk remains on the PUP list recovering from ACL/MCL surgery, Jordan Watkins is dealing with a high-ankle sprain, and Demarcus Robinson is set to serve a three-game suspension.
• The 49ers traded for Skyy Moore to bolster receiver depth, and coaches noted he picked up elements of the offense quickly after arriving.
