There was concern for the British and Irish Lions when captain Alun Wyn Jones was forced off early in Saturday's Test against Japan.
Jones was withdrawn after doing damage while trying to turn the ball over in the eighth minute of the match at Murrayfield.
The lock appeared to injure his left wrist and walked off the field shaking his head in the warm-up match ahead of the tour of South Africa.
Jones, the most-capped player in Test history, was replaced by England lock Courtney Lawes.
The Lions start the three-match series against the Springboks at Cape Town Stadium on July 24.
