BEIJING, Dec. 8 (Xinhua) -- Zhengjiang Guangsha coach Li Chunjiang has been suffering from a chest bone fracture after he accidently clashed with players in training.

The feisty coach was particularly quiet in Sunday's CBA game where Zhejiang beat Jiangsu 109-101.

Chinese news portal Sina reported that Li was directing the game with a chest bone fracture which was sustained in an accidental crash into his players in earlier training.

Doctors suggested the 51-year-old to talk less, on court and out of.

Li was a famous basketball player in China and also known for his short temper.

He led his players to boycott a quarterfinal game against Syria in U18 Asian championship in 2008 over controversial judging.

In 2013, he stepped down as Guangdong coach after bringing the team to seven league titles. Li cited health reasons but some speculated that his fiery temper could have something to do with his departure.
