Overview

• John Lynch said on KNBR that Brandon Aiyuk remains “not close” to returning from last October’s multi‑structure knee injury, noting no setbacks but emphasizing milestone-based rehab.
• Aiyuk opened the season on the PUP list and becomes eligible to practice next week, which would start a three‑week window to activate him or move him to season-ending injured reserve under NFL rules.
• Kyle Shanahan said Brock Purdy’s toe is improving and he should be ready Sunday if progress continues, and Purdy said he feels “a lot better” after back-to-back limited practices.
• San Francisco activated wide receiver Demarcus Robinson from a three-game suspension, and he rejoined drills at the front of the receiver line to bolster a thin position group.
• George Kittle is progressing on short-term IR with a hamstring and is first eligible for Week 6 at Tampa Bay, and Nick Bosa went on season-ending IR with ACL surgery scheduled in Los Angeles.
