Kolkata Knight Riders survived a late charge by Royal Challengers Bengaluru batsmen to win by one run in an IPL thriller after Virat Kohli's angry outburst at his dismissal on Sunday.

Bengaluru conceded 222-6 after electing to field first at Kolkata's Eden Gardens with Phil Salt smashing 48 off 14 balls and skipper Shreyas Iyer hitting 50.
