Brock Purdy did not play recently because he suffered a setback with a turf toe injury. After initially missing Weeks 2 and 3 due to the injury, he returned in Week 4 but experienced soreness afterward. An MRI confirmed aggravation of the injury, and as a result, he was ruled out for Week 5 and is considered week-to-week. The quick turnaround to a Thursday Night Football game made recovery more challenging. The 49ers are cautious about his health, assessing whether he can perform at 100% and protect himself while playing. Backup quarterback Mac Jones has been starting in his absence.
