Dubai, Mar 29: Sri Lanka will lose their number one status in ICC Twenty20 International Ranking if they are beaten by Bangladesh in the one off game at Pallekele International Cricket Stadium on Sunday.
Sri Lanka lead ninth-ranked Bangladesh by 47 ratings points and this gap means Sri Lanka are favourites to win the one-off match.
As such, because the rankings are weighted to reflect this difference, failure to win the match will mean Sri Lanka will drop five ratings points and slip one ratings point behind the second-ranked West Indies, an ICC media release said on Friday.
However, if Sri Lanka win the match, then they will gain one ratings point and will extend its advantage over the West Indies to six ratings points.
Sri Lanka's victory will, however, cost Bangladesh a drop of two ratings points that will put it at par with Ireland on 82 ratings points, but ahead of the Associate side when the ratings are calculated beyond the decimal points.
Meanwhile, the one-off match on Sunday will also herald the start of a new era for Sri Lanka in the format.
Sri Lanka will be led by wicketkeeper-batsman Dinesh Chandimal for the first time in the format with fast bowler Lasith Malinga being his deputy.
Chandimal will miss the services of experienced former captains Mahela Jayawardena, Kumar Sangakkara and Tillakaratne Dilshan.
