In a significant setback at the beginning of Mumbai's Ranji Trophy campaign, newly appointed vice-captain Ayush Mhatre has sustained a Grade 4 tear in his right hamstring, leaving him facing a prolonged period on the sidelines.

The 19-year-old opener is anticipated to miss four to six weeks of competitive action, although recovery timelines for a Grade 4 tear often extend up to three months depending on rehab progress and injury severity.
