Gabon have sent Pierre-Emerick Aubameyang back to Arsenal for medical examinations after he was diagnosed with heart lesions.
The 32-year-old had recently tested positive for COVID-19 but has returned to training since and felt healthy. Arsenal are still waiting for confirmation from the Gabon Football Federation.
The Premier League club said last week they had been in touch with Aubameyang and are confident his condition is not serious.
The Arsenal striker has missed Gabon’s first two group matches at this year’s Africa Cup of Nation and would also miss the final group game against Morocco on Tuesday.
The forward tested positive for coronavirus on his arrival in Cameroon for the tournament, but he returned a negative test last week before training on Thursday.
Aubameyang, along with team-mates Mario Lemina and Axel Meye, were shown to have “cardiac lesions” following fights with COVID-19.
