From the Washington Post's (and TSL favorite) Michael Lee

In his first interview in more than a month, Wall admitted Monday he has developed cartilage damage underneath his left patella. His continued absence three months after the diagnosis of a non-traumatic stress injury has opened the door for more speculation about when — or if — he’ll return this season.

Looks like it might be a while before we get to see that Wall-Beal backcourt.
