Kruger van Wyk, the South Africa-born Central Districts wicketkeeper, has been added to New Zealand's squad for the South Africa Tests as cover for BJ Watling, who has a hip injury. The first Test starts on Wednesday. van Wyk himself hadn't batted on Sunday in CD's Plunket Shield match against Auckland due to an illness.

"Watling has been suffering from some irritation around his hip joint," New Zealand's physiotherapist Paul Close said. "We're monitoring it closely and will know more in the next 24 hours, after he has completed training and had time to rest."

Watling and van Wyk had both been in contention for the wicketkeeper's spot before the Test against Zimbabwe in January. Watling was picked for the final XI and scored his maiden Test century to reinforce his position as the current first-choice gloveman.
