Vinicius Junior got off injured, and was subbed off just 27 minutes into Brazil’s game against Colombia.
Medical staff had to place a cumbersome ice bandage on his thigh, and he has since returned to Madrid.
Talking to the media after the game, Vinicius explained: “I got a knock there and felt pain a little later. I think it’s the same injury [I had before] but tomorrow we’ll have the tests and see.”
According to a report from reporter Jose Luis Sanchez, Vinicius could miss up to six weeks.
Meanwhile, Real Madrid have announced that the Brazilian tore his femoral biceps which is quite a serious injury.
A statement from Real Madrid reads: “Following tests carried out today on our player Vinicius Jr. By the Real Madrid Medical Services, he has been diagnosed with a tear in his left femoral bicep which is affecting the tendon in his hamstring. His recovery will be monitored.”
