Jennings is expected to play through a shoulder injury as the 49ers face the Saints, with Williams’ knee also up in the air and a pregame test looming. Purdy’s toe and shoulder issues linger, but progress has been noted; Mac Jones will start in Purdy’s stead, reshaping the offense if needed. If Williams can’t go, Burford steps in at left tackle, tightening the fantasy lines behind a vulnerable edge. Week 3 vs Arizona remains murky until Purdy is cleared.
