Lions: 5-0 (1 over)
Quinton de Kock and Rassie van der Dussen open the batting for Lions and it will be Mitchell Johnson first up for Mumbai. Five runs come off the first five balls.
The match is then delayed by a floodlight failure.
Mumbai Indians were beaten by Rajasthan Royals in their opening match and their second outing against Otago Volts was washed out.
Thus, the IPL winners are eager to stamp their authority in this do-or-die battle against Highveld Lions.
Like Mumbai, the Lions also lost to Rajasthan Royals, while the other against Perth Scorchers was abandoned.
Both teams have just two points from as many outings.
Mumbai Indians: Rohit Sharma (capt), Sachin Tendulkar, Dwayne Smith, Dinesh Karthik, Kieron Pollard, Ambati Rayudu, Nathan Coulter-Nile, Harbhajan Singh, Rishi Dhawan, Mitchell Johnson, Pragyan Ojha.
Highveld Lions: Alviro Petersen (capt), Quinton de Kock,
Rassie van der Dussen, Neil McKenzie, Jean Symes, Dwaine Pretorius, Sohail Tanvir, Hardus Viljoen, Aaron Phangiso, Lonwabo Tsotsobe, Imran Tahir.
