Mitchell Santner, the 34-year-old captain of New Zealand's white-ball cricket team, has been diagnosed with a grade three ACL shoulder injury, which will keep him out of action for at least a month. The injury occurred during a match for the Mumbai Indians (MI) against the Chennai Super Kings (CSK) on April 23. After returning to New Zealand, scans confirmed the severity of the injury, leading to a rehabilitation period. As a result, Santner will miss the upcoming one-off Test against Ireland and the first Test against England at Lord's in early June. Santner had played four matches for MI this season after joining the squad late, having previously requested time off for personal reasons. He was instrumental in leading New Zealand to the T20 World Cup final, where they lost to India. Despite the setback, he is expected to return in time for the ODI and T20I series against the West Indies in July.
