Kyrie Irving

Irving apparently suffered the injury while training in early July, but the severity of the injury and a potential timeline for return are unknowns.

The Mavericks announced Tuesday that Irving underwent surgery to repair a broken left hand that he sustained earlier this month while training, Michael Scotto of USA Today reports.

A timeline for Irving's return wasn't made clear.

Irving injured his hand training, according to the team, but the details of the injury are not public.
