Chelsea forward Eden Hazard has fractured his 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 one of their key players.
Earlier on Sunday, Hazard cast doubt over his Chelsea future by admitting he would have to listen to an offer from Real Madrid if the Champions League winners come calling this summer.
“Of course, I would consider it. I am keen to win trophies. It would be great to win the Champions League. But Chelsea’s goal is to win the Champions League as well. Honestly, I do not know what will happen.”
