The 26-year-old playmaker sustained the injury training with the national side and will miss Monday's friendly against the Czech Republic and a 2018 World Cup qualifier in Estonia on Friday.

A tweet from his national team read: "Medical imaging showed that @hazardeden10 has a fracture in his right ankle #belcze #estbel #roadtorussia."

Hazard -- who helped lift Chelsea to the Premier League title last season -- will undergo surgery Monday and could be out for four months, according to press reports.
