South Africa quick Dale Steyn may require surgery after fracturing a bone in his shoulder on a dramatic day two of the first Test against Australia at the WACA.
The Proteas paceman has been ruled out of the rest of the three-match series and will fly home as a result of another injury blow sustained in Perth on Friday.
South Africa's premier fast bowler clutched his right shoulder after bowling a delivery in the morning session, having dismissed David Warner (97) to spark an incredible Australia collapse.
The 33-year-old damaged the same shoulder in the first Test against England last December and his participation in the series against Australia is now over just a day after it started.
Proteas team manager Dr Mohammed Moosajee said: "Dale pulled up while bowling shortly before lunch complaining of severe pain to his right shoulder.
"He was taken to the hospital for scans which confirmed a new fracture of the bone in the shoulder joint. He will take no further part in the match [he will bat if absolutely necessary] and the series, and will return to South Africa to see a shoulder specialist who will advise on the appropriate plan of action.
"An injury of this nature is rare and will in all likelihood require surgery but that will only be confirmed once we receive an opinion from the specialist."
Steyn's injury took the gloss off a magnificent day for the tourists, who skittled Australia out for 244 after they had been 158 without loss and closed on 104-2 to lead by 102 runs in a remarkable turnaround.
Morne Morkel is the obvious choice to replace Steyn for the second Test in Hobart.
