Neymar injury explained
Neymar was sent off and immediately showed off his swollen ankle on his way to the bench.
Pictures of his injury flooded social media and Brazilian football fans worried about his continuation at the tournament.
Brazil boss Tite has now provided an update on his star striker’s injury and is reassuring football fans that he will be fine.
He said: “You can be sure that Neymar will play at the World Cup, I’m absolutely sure of that. He’s going to play at the World Cup.
“Exactly with regard to Neymar, I want to make a technical and tactical comment. He kept feeling his ankle in the two goals we scored, because the team needed him.
“The two goals, one of which was decisive, had the ability to overcome his pain and were present on both goals.”
Dr. Rodrigo Lasmar explained that Neymar’s injury is not as bad as initially feared and that he is not expected to be sidelined for long.
He said: “Neymar had a sprain in his right ankle, a direct trauma when his opponent’s knee made a movement that caused the sprain.
“He had some swelling in his ankle, we started the treatment with ice on the couch and he has now undergone the physiotherapy treatment.
“There is no planned imaging study. If there is a need, we will. But that will be determined tomorrow by the measure of his evaluation.
“The expectation is observation. Everything we talk about evolution, its sequel, is premature. We have no answers, it is important to wait.”
Brazil will return to action against Switzerland in their next group stage match scheduled for Monday, November 28, 2022.
