The striker's thigh injury is not as bad as first feared and he could be fit to face Andre Villas-Boas' side, but he will not be available to play in Ghana's friendly with Brazil
The 25-year-old was stretchered off during Ghana’s 2-0 victory against Swaziland on Friday and it was initially thought that he may be out of action for several weeks.
However, Ghana’s team doctor, Percy Anan, has confirmed that the forward’s injury is not as bad as first feared.
Anan told the Ghanaian FA’s official website: "The scans revealed that there was no muscle tear in his thigh but he felt contusion in the area. He would be able to return to action soon."
Despite looking set to feature for Sunderland against Chelsea, Gyan will not be available to play in Ghana’s friendly against Brazil on Monday.
The striker said: "I would have really wished to feature in this one but I totally understand what the medics are saying. It's fine by me and I will cheer the guys on."
Meanwhile, Gyan’s Sunderland team-mate John O’Shea has been ruled out of the Republic of Ireland’s Euro 2012 qualifier against Russia due to calf and hip strains.
