Bulls number eight Pierre Spies will not travel to Europe with the Springboks in November due to the slow recovery of a finger injury.
Spies underwent successful surgery on the fracture to the joint in his finger in August and was hence ruled out of the Rugby Championship has been on a rehabilitation programme and running at Loftus since.
On Thursday the Bulls captain confirmed that he will be sidelined for the remainder of the year.
"I was hoping to [play again this year], but the finger is healing slowly, so next year is more likely," Spies told SuperSport.
The news will come as blow for Springbok coach Heyneke Meyer, who is short on options at number eight since Ryan Kankowski's departure for Japan.
