Mitchell Santner, the captain of New Zealand's white ball cricket team, will be out of action for at least one month due to a grade three ACL shoulder injury. The injury occurred on April 23 while he was fielding during a match between the Mumbai Indians and the Chennai Super Kings in the Indian Premier League. Santner, 34, suffered the injury while attempting a diving catch and subsequently hit his shoulder and head on the ground. Following his return to New Zealand, a specialist confirmed the need for a rest and rehabilitation period. As a result, he will miss the one-off four-day Test against Ireland, which begins on May 27 in Stormont, Belfast, and the first Test against England, scheduled for June 4-8 at Lord's. New Zealand Cricket has stated that Santner's availability for the second and third Tests will be evaluated at a later date.
