LONDON: India captain Virat Kohli has ruled out participating in the initial stages of the England and Wales Cricket Board's new 100-ball format and says he is worried that commercial concerns are eroding the quality of the game. The ECB's new eight-team tournament is set to begin in 2020 and sees each side facing 15 six-ball overs, culminating in a final 10 deliveries. Kohli already represents India in tests, one-day internationals and Twenty20s and plays in the Indian Premier League and said he did not want to be 'a testing sort of cricketer for any new format... ' 'Obviously for the people involved in the whole process and the set-up it will be really exciting but I cannot think of one more format, to be honest,' Kohli said in an interview with Wisden Cricket Monthly. 'I am very ... I wouldn't say frustrated but it can get very demanding of you when you have to play so much cricket. I feel the commercial aspect is taking over the real quality of the cricket and that hurts me.'
