Tottenham striker Richarlison was in tears after victory over Everton.
The Brazilian limped off seven minutes into the second half of Tottenham's victory over former club Everton, indicating to the bench he had felt a pull in a calf muscle.
It left him close to tears with boss Antonio Conte confirming the £60million striker will be sent for a scan.
"We don't know, we hope it is not so serious," said Conte. "He felt a problem in his calf. He will have an MRI to understand it tomorrow, we hope it is not serious."
Richarlison said, "The last time when I was at Everton, I was out of action for about two months.
"I know it's hard to talk at this moment, but let's see, I'll recover. Monday, I have an exam but even walking hurts. I have to stay positive if I want to go to Qatar.
"It's all so close, it's about a month to go, and we've been getting ready, working every day so that nothing serious can happen. Unfortunately, today I had this calf injury, but now it's just a matter of waiting, doing the treatment every day so that I can recover as soon as possible."
