Dickwella handed two-match ban for dissent

Updated: 

Sri Lanka wicketkeeper Niroshan Dickwella has been suspended for two limited-overs matches for showing dissent.

Dickwella was found guilty of "showing dissent at an umpire's decision" during his side's win over Australia in their second Twenty20 on Sunday, the ICC said.

He received a 30 per cent fine and two demerit points, the latter taking his tally to five within a 24-month period - leading to the suspension.

Dickwella will miss the third T20 against Australia in Adelaide on Wednesday, and likely a meeting with Bangladesh on March 25.

Given out caught behind for 14, Dickwella was seemingly unhappy with the decision and, according to the ICC, "paused to view the replay, kicked the turf and looked at his shoulder for a prolonged period of time".

Australia wicketkeeper Tim Paine was fined 15 per cent of his match fee and received one demerit point for using inappropriate words after Dickwella was given out.

Sri Lanka have already sealed the three-match series against Australia after thrilling wins in Melbourne and Geelong.
