England opener Rory Burns is likely to miss the Sri Lanka series in March with the ankle injury which ended his tour of South Africa.
The 29-year-old suffered ligament damage to his left ankle while playing football during practice before the ongoing second Test in Cape Town.
He will see a specialist next week to determine if he needs surgery.
Keaton Jennings is the leading contender to replace Burns for the two-Test series starting on 19 March.
England have yet to decide whether to call up a replacement for Burns for the final two Tests of the current series, which South Africa lead 1-0.
National selector Ed Smith has arrived in Cape Town and will discuss the options with head coach Chris Silverwood.
Burns, who top-scored for England with 84 in the first-Test defeat in Centurion, averages 33.75 in 15 Tests.
England have since banned playing football during practice.
Jennings averages 25.19 from 17 Tests since making a century on debut in India in 2016.
Opening with Burns, he scored 233 runs at 46.60 in England’s 3-0 series win in Sri Lanka in 2018, including an unbeaten 146 in the first Test in Galle. (Courtesy BBC Sports)
