An umpiring howler off the last deliver cost Royal Challengers Bangalore dearly as Mumbai Indians pipped the hosts by six runs largely due to Jasprit Bumrah's brilliant spell at the death in an IPL encounter on Thursday.

Needing six to take the game into Super Over, Lasith Malinga's final delivery to Shivam Dube was a no-ball that was missed by the on-field umpires as RCB managed 181 for 5 in reply to 187 for 8 by Mumbai Indians.
