McFaul posted a picture to Twitter in which his finger is blue and swollen, RIA Novosti reported.
Initially McFaul captioned the picture "physical therapy," but later added "broken finger, playing basketball."
The injury comes about two months after McFaul broke the same finger while playing basketball. McFaul needed surgery as part of his recovery from the November injury.
