49ers WR Brandon Aiyuk tore the ACL and MCL in his right knee in the Week 7 loss to the Chiefs, according to NFL Network's Ian Rapoport. "There may be other damage," Rapoport adds. Aiyuk will miss the rest of the 2024 season. And any "other damage" to his knee could impact his availability for the start of the 2025 campaign. We'll keep you updated on Aiyuk's diagnosis and timeline for return.

49ers HC Kyle Shanahan said after Sunday's loss to the Chiefs that "we're worried" WR Brandon Aiyuk has a torn ACL. "Not confirmed yet," Shanahan added. We should get an update on Aiyuk tomorrow, but a torn ACL would end his 2024 season. His absence would mean target boosts for WR Deebo Samuel and TE George Kittle -- and put WR Jauan Jennings back into weekly starter consideration.

49ers QB Brock Purdy is "day-to-day" with back soreness, HC Kyle Shanahan said Monday. Purdy had an MRI that came back clean, per Shahanan, and the team is hopeful that he'll be able to practice on Wednesday. It doesn't sound like this is something that'll impact Purdy's Week 4 outlook, but we'll keep an eye on him this week.

Niners TE George Kittle missed practice with hamstring tightness Thursday. ESPN's Adam Schefter reports that the TE's status for Sunday's game against the Rams "is in question."
