Injury Notes

As expected, quarterback Brock Purdy (left shoulder, toe) did not practice and will miss Sunday's game. Mac Jones is set to make his first start with the 49ers. The team will elevate Adrian Martinez from the practice squad to serve as Jones' backup.

Jones could face a challenging debut as the team's starting left tackle, Trent Williams (knee), is uncertain for Sunday. He was limited in practice after not participating earlier in the week.

On a positive note, wide receiver Jauan Jennings (shoulder) returned to practice Friday after not participating earlier in the week. Williams and Jennings are "questionable" to play.
