It is expected that the fracture will heal on its own with rest and Young will make a complete recovery but it is not yet clear if he be able to play again this season.
Young has missed the last 11 games with a swollen left knee and has no played since the Lakers beat the Boston Celtics 118-111 on Feb. 22.
"Nothing," Lakers coach Byron Scott said when asked what Young was able to do at practice. "He signed some autographs, went back in and got some treatment and that was about it."
Young is averaging 13.4 points and 2.3 rebounds in 23.8 minutes over 42 games this season.
Young did not practice on Wednesday but was sporting a new hairstyle he said was inspired by Kid 'n' Play and Jamie Foxx.
"I felt like it was time for a change," Young said. "I was watching Kid 'n' Play at home and then I started watching Booty Call and I said Jamie Foxx has a nice hairstyle I want to try so that's the inspiration behind it."
Scott wasn't a fan of the hairdo, saying it looked like Young lost a bet.
"It looked like a bunch of worms up there just running around," Scott said. "When I first saw him I started cracking up, laughing."
Young laughed when he was relayed Scott's thoughts on his hair.
"People with no hair wouldn't understand," Young said. "When you have the ability to try things with your hair but when it's over with you tend to turn into a hater on people that got hair. I would be mad at someone with hair if I didn't have hair."
