Du Plessis fell awkwardly while attempting a catch during the third One-Day International (ODI) at Pallekele on Sunday, and was unable to field for the rest of the match.

Proteas team manager, Dr Mohammed Moosajee explained the injury: "Faf sustained an injury to one of the rotator cuff tendons in his right shoulder and will unfortunately be unavailable for the rest of the tour. He will need a rehabilitation period of up to six weeks to make a full recovery. His return date back to South Africa will be confirmed in due course."

The selectors will name the stand-in captain for the remainder of the ODI series and one-off T20I on Tuesday.

There will be no replacement added to the squad.

The Proteas, meanwhile, have taken unassailable 3-0 lead in the five-match series against Sri Lanka. The 4th ODI takes place in Kandy on Wednesday (11:00 SA time).
