Juventus defender Giorgio Chiellini will regain his fitness in time for his side's Serie A clash against Napoli in Naples on Friday.

The 28-year-old centre-back made his comeback from a calf injury on Sunday when he came on as a second-half substitute against Siena in their 3-0 home win.

Chiellini suffered an ankle problem during the match and was forced to come off the pitch, but a medical examination has ruled out any major concerns.

"Following this afternoon's game against Siena, Giorgio Chiellini underwent a number of x-rays after reporting discomfort in his right ankle," reads a statement on Juventus's official website.

"The tests ruled out any bone or ligament damage and mean the defender has merely sustained heavy bruising."

Juventus are currently six points clear at the top of Serie A.
