Chennai Super Kings captain Mahendra Singh Dhoni escaped a ban and was let off with a 50 per cent fine on his match fee for an unprecedented confrontation with the on-field umpire during the IPL encounter against Rajasthan Royals here.

In a rare instance, Dhoni, who was not even meant to be on the field of play, lost his cool and rushed out of the dug-out to challenge umpire Ulhas Gandhe after he flip-flopped on a no ball on Thursday night.
