Chennai Super Kings have been dealt a major blow with young batter Ayush Mhatre sustaining a hamstring tear which "looks pretty bad" during their IPL match against Sunrisers Hyderabad here.

The 18-year-old, who came in as an impact substitute, appeared in visible discomfort and clutched his hamstring while attempting a run, requiring on-field treatment during CSK's 10-run loss to SRH here on Saturday.
