Ghana's World Cup opponents, Serbia are likely to miss striker Danko Lazovic for the tournament as he has been  ruled out for a month with a thigh injury.
Lazovic will be out for a month with a thigh injury he picked up in a Russian Premier League match for his club Zenit St. Petersburg against Terek Grozny.
Lazovic's participation in the World Cup finals is hanging in the balance as they face Ghana in Group D of the tournament to be held in South Africa.
The initial scan on Monday revealed a torn muscle.
"I felt sharp pain as I ran after the ball and I am really concerned about the World Cup, the second scan will show how serious the injury is," Lazovic said.
The injury is a second blow in a week for Serbia, who have lost defender Ivica Dragutinovic to a torn Achilles tendon and he is certain to miss the June 11-July 11 finals.
