Mitchell Starc has been ruled out of the 2018 Indian Premier League (IPL) due to a right leg injury. Starc, who was picked by Kolkata Knight Riders (KKR) for a whopping Rs 9.4 crore at this year’s auction, had injury issues in the ongoing Test series against South Africa, revealed Tim Paine. Starc has a ‘tibial bone stress in his right leg’. He will return home for further assessment after the Johannesburg Test. He becomes the third Australian to be ruled out of this year’s tournament. Earlier this week, the Board of Control for Cricket in India (BCCI) barred Steve Smith and David Warner for their roles in the ball-tampering scandal.The Australian left-arm pacer will be missing the tournament for the third year in a row. Last year, Mitchell Starc ended his association with Royal Challengers Bangalore (RCB) to focus on international cricket, while in 2016, a foot fracture kept him out of the tournament. In 27 IPL matches, Mitchell Starc has 34 wickets at an economy rate of 7.17. Sans the 28-year-old fast bowler, KKR will now depend more on compatriot Mitchell Johnson. It is understood that in accordance with the Player Regulations, KKR will now be allowed to choose a replacement from the Registered and Available Player Pool (RAPP).Two-time champions KKR open their IPL 2018 campaign against RCB on April 8.
