Brazil forward, Neymar Jr, left the pitch with a knee injury as they lost 2-0 to Uruguay in a 2026 World Cup qualifier on Tuesday.
Neymar was in tears as medics stretched him off at the end of the first half.
The former Paris Saint-Germain star was later seen leaving the stadium on crutches.
The 31-year-old tripped and fell during a run in the 44th minute at the Centenario Stadium and was immediately surrounded by players from both teams as he held his left knee.
He was eventually replaced by Richarlison.
Brazil team doctor, Rodrigo Lasmar said after the game that Neymar had already undergone tests and that more would be done on Wednesday.
“These 24 hours will be important to see how the knee will respond, how the swelling will be,” Lasmar said.
“Imaging tests that will define a definitive diagnosis. It’s too early to say [if it’s a ligament injury]. Let’s wait for the exams calmly, evaluate calmly, and as soon as we have a definition we will let you know.”
