The latest I have heard (this information is from Twitter and is about half a day old) is that Saka has trained, and Calafiori will have just had a scan on his knee.
There has been some prognostication going on among fans about Calafiori's knee strain.
The claim is that it might only be a fortnight till he can return if it's a minor issue, all the way through to 10 weeks or start of 2025 if he did his MCL. The same people are saying the movement which caused the injury means it's not his ACL.
