Australian fast bowler Pat Cummins has been ruled out of the Indian Premier League with a back injury.

The 24-year-old was signed for the Mumbai Indians for the Twenty20 tournament which started at the weekend.

But he suffered soreness during the fourth Test in South Africa and scans revealed a bone oedema in his vertebrae.

Team physiotherapist David Beakley said: “It is important that Pat has time off bowling, to prevent the injury becoming more serious and consequently we have made the decision to rule Pat out of the IPL.

“Pat will now undergo a period of recovery and rehabilitation and we will look to re-scan him in a few weeks to assess the healing.

“Following this we will be in a better position to decide on Pat’s return to play timeline including participation in the limited overs tour of the UK.”
