BENGALURU: Karnataka were dealt a huge blow on the eve of their quarterfinal against Tamil Nadu as their in-form batsman R Samarth and off-spinner K Gowtham have been ruled out of the tournament due to injury. Both are expected to return home on Tuesday. Samarth, the highest run-getter for Karnataka in the competition, fractured his left little finger during the pre-quarterfinal against Rajasthan. Gowtham, who joined the team for the knockouts after returning from India’S ‘A’ tour of South Africa, has a grade 2 medial meniscus injury in the left knee.
