The ASB Classic doubles final, featuring Kiwi Michael Venus, will not go ahead.
American veteran Rajeev Ram has pulled out through injury, notifying the tournament organisers at 10am on Saturday.
Ram, who was paired with compatriot Christian Harrison, suffered the injury in the semifinal last night and was unable to overcome it, despite treatment on Friday night.
Instead of the final, a doubles exhibition will be played with Kiwi Isaac Becroft stepping in to partner Harrison against Venus and Mektic.
Tournament director Nicolas Lamperin said injuries are always a shame, particularly ahead of a final.
