Ghana have injury and suspension headaches ahead of a World Cup quarter-final against Uruguay at Soccer City here on Friday.
"My ankle is a bit swollen but I do not think it is too serious. I will be ready for Uruguay," he assured reporters as he watched his team-mates practice with ice wrapped around the ankle.
He scored the late winner against Serbia from a penalty, equalised against Australia from another spot kick and unleashed an extra-time thunderbolt that floored United States in the second round last weekend.
Boateng worsened a hamstring problem he took into the USA clash and his situation is worrying Serb coach Milovan Rajevac as he will lack suspended defender Jonathan Mensah and influential midfielder Andre Ayew.
Mensah from English Premiership club Sunderland has struggled with a back problem for some time but is expected to start and could be partnered by Isaac Vorsah with Jonathan Mensah ruled out after two cautions.
Ayew, one of two sons of three-time African Footballer of the Year Abedi 'Pele' Ayew in the squad, has been an ever-present in South Africa before a second yellow card ruled him out.
Among those who could replace Ayew is 'bad boy' Sulley Muntari from European club champions Inter Milan, who has clashed regularly with arch disciplinarian Rajevac since he succeeded Frenchman Claude le Roy two years ago.
Dressingroom criticism of the coach after a group draw with Australia almost led to him being kicked out of the squad and officials have admitted he is on a final warning.
Muntari refused to play in a friendly against Angola last November, leading to his exclusion from the African Nations Cup two months later in which severely depleted Ghana finished runners-up behind Egypt.
