Juventus defender Stephan Lichtsteiner has been forced to undergo an operation on his heart after suffering with breathing difficulties.
Lichtsteiner was substituted after complaining of the problem in the 1-1 draw with Frosinone last Wednesday and it has been revealed that the Swiss defender was diagnosed with arrhythmia.
"During last week's match with Frosinone, Stephan Lichtsteiner suffered breathing difficulties due to a benign cardiac arrhythmia which later stopped of its own accord," a club statement confirmed.
"Tests and specialist consultancy conducted over the following days suggested surgery to be the best course of action for the defender.
"Dr Gaita today performed a cardiac ablation operation and Lichtsteiner is expected to return to competitive action within 30 days."
Juventus host Bologna in Serie A on Sunday.
