Mitchell Santner, the 34-year-old captain of New Zealand's white-ball cricket team, has been sidelined for at least a month due to a grade three ACL shoulder injury. The injury occurred on April 23 while he was fielding in a match between the Mumbai Indians and Chennai Super Kings during the Indian Premier League (IPL). Santner sustained the injury while attempting a diving catch, resulting in a hard impact on his shoulder and head. Following his return to New Zealand, he consulted a specialist who confirmed the need for a rest and rehabilitation period. As a consequence, he will miss the upcoming one-off Test against Ireland starting on May 27 in Belfast, as well as the first Test against England scheduled for June 4 at Lord's. New Zealand Cricket (NZC) has stated that his availability for the second and third Tests will be assessed at a later date.
