Real Madrid's Brazilian forward Vinicius Jr could be out for two months after tearing ligaments in his right ankle during the defeat by Ajax in the Champions League.

A Real Madrid statement said the 18 year old, who received his first Brazil call-up last week, has a "torn ligament of the tibiofibular joint in the right leg".

The striker has made 28 appearances this season for Real after joining from Brazilian side Flamengo in the summer.
