Ghana captain Asamoah Gyan could spend some more time in the treatment room after limping off in a Chinese Super League game on Saturday.
The 29-year-old lasted only 18 minutes as Shanghai SIPG lost 3-0 at home to Guangzhou Evergrande, after appearing to have aggravated an unhealed injury.
Robinho, Ricardo Goulart and Erikeson each scored as Luiz Felipe Scolari’s side moved two points clear on top of the league standing.
Gyan went into the game having missed the Black Stars’ 1-0 win over Rwanda in the 2017 Africa Cup of Nations qualifier in Kigali on September 5 due to similar injury worries.
The former Udinese man failed to pass a late fitness test for the encounter after picking up a knock in Ghana’s 3-2 win over Congo in an exhibition game four days earlier.
Gyan is expected to undergo further tests to evaluate the extent of his latest setback.
The striker joined the Chinese outfit in July in a two-year deal from United Arab Emirates’ side Al Ain and has so far scored four times in seven appearances for his new club.
In a largely successful stay in the Arabian Golf League, Gyan scored 95 goals in over 83 matches, as he helped Al Ain to three league titles, the 2014 President’s Cup as well as the 2012 Arabian Gulf Super Cup.
He was also adjudged top scorer in the AFC Champions League in 2014 and the 2014 AFC Foreign Player of the Year.
