49ers RB Christian McCaffrey (calf) limited in Thursday's practice

49ers GM John Lynch told @KNBR that WR Brandon Aiyuk is “not close” to returning from the knee injury he suffered almost a year ago. There was more damage than just to the ACL, and more recovery time is required.

This aligns well with Jeff Mueller's assessment that Aiyuk's most likely return would be in Week 6, but the wording suggests a potential that it may last even longer. He remains a good stash — particularly if you have an IR spot — but it still looks like we're weeks away from it changing the remaining 49ers' pass-catchers' target share.

Justin Fields will practice today, but he's still in concussion protocol.

HC Aaron Glenn later reiterated that Fields would start if cleared before Monday, so it seems like there's a good chance he suits up for Week 4. If he's cleared before we have to set lineups on Sunday morning, we can inch him up to a low-end QB1 in what should be a pretty nice matchup.

Chiefs listed WR Xavier Worthy as a full participant in today’s practice, putting him on track to play Sunday against Baltimore.

Since his massive 16-target performance after Worthy went down in Week 1, Brown has been completely forgettable in his two chances to earn more work since. If Worthy is looking close to 100% this early in the week, we should definitely consider him further up our rankings than if he weren't a full participant until Friday. Push him up into the WR2/3 range if he is completely cleared ahead of the weekend.
