Watch: Height of bad luck! Powercut in stadium leaves DRS disabled - Fans react as Devon Conway and Robin Uthappa can't review LBW calls
In a bizarre event at the Wankhede stadium, a powercut meant the DRS wasn't working at the start of the game and it made an immediate impact when Devon Conway was adjudged LBW off a delivery going down the leg side from Daniel Sams in the first over. With no DRS, the CSK batter couldn't review the decision although he wanted to and he had to walk off.
Soon after, CSK lost Moeen Ali as well, and then obin Uthappa was again adjudged LBW next over off Jasprit Bumrah. With another contentious decision going against them, CSK were left frustrated with no reviews to take. Soon after Uthappa's dismissal, power returned in the stadium and DRS was available again.
Reduced to 5/3 inside two overs, CSK were in dire straits in the big game against Mumbai Indians.
