Chelsea forward Eden Hazard has suffered a fractured ankle while on international duty with Belgium.
Hazard incurred the injury in training at the National Football Centre in Tubize on Sunday and was ruled out their friendly against the Czech Republic on Monday and the World Cup Qualifier in Estonia on June 9.

A subsequent scan revealed the problem to be more serious than was first realised and Hazard could now be out for up to eight weeks, a timescale that would affect his pre-season preparations with Chelsea.
Belgium are top of World Cup Qualifying Group H, two points ahead of Greece, after winning four and drawing one of their five matches but they must now do without their talismanic playmaker.
