Chelsea striker Nicolas Jackson picked up an injury while playing for his country’s national team.

Nicolas Jackson sustained the injury in Senegal’s 1-1 draw against DR Congo in a World Cup qualifier.

In an official statement, the Senegalese FA described the issue as ‘a serious sprain of the ankle’.

Chelsea now fear that Nicolas Jackson might miss the start of pre-season due to a serious ankle sprain sustained during Senegal’s World Cup qualifier against DR Congo.

The injury could impact his preparations, though there is hope he will join the team for their U.S. tour, starting with a friendly against Wrexham on July 24.
