Perpignan’s 40-14 victory over Bourgoin may have come at a price as Dan Carter left the field with an injury at half-time.
The All Blacks flyhalf said it was a recurring Achilles tendon injury and the decision to further sideline the star will only be made this Monday following further medical tests.
“The pain was getting worse after about half an hour of the match and as a precaution I came off at half-time. It was frustrating because I really wanted to play and the team had a really good match,” he said.
