Brazilian striker Richarlison faces an agonizing wait to find out the extent of an injury that forced him out in Tottenham Hotspur’s Premier League victory against Everton on Saturday.

Richarlison has established himself as Brazil’s “9” and is the favorite to lead the team’s attack at the World Cup in Qatar, which begins next month.

But he limped off early in the second half with a calf injury and will undergo an MRI on Monday.

Tottenham manager Antonio Conte has ruled Richarlison out for a visit to Manchester United next week, but there are fears the injury could force him into a long spell of inactivity.

Richarlison, who has scored 17 goals in 38 games for Brazil, left Tottenham’s stadium on crutches and was emotional when being interviewed after the game. “It’s a bit difficult to say because it’s close to the realization of my dream (the World Cup),” he told ESPN Brasil.

“I already had an injury similar to this one, but I hope it can heal as soon as possible. Last time, when I was at Everton, I was out for about two months.”

“It’s hard to talk at the moment, but let’s see, I will recover. I have a scan on Monday, but even walking hurts. I have to be positive if I want to go to Qatar.”
