India is currently the second ranked Test team behind Australia.
The change in ranking was a result of a major glitch in the ICC website as neither India nor Australia are presently part of any Test series and are slated to play one, against each other, next month. ICC Test rankings tend to change only at the end of every series.
The last time ICC changed the rankings were at the end of the three-Test series between Australia and South Africa. The table was updated on January 8 after Australia had defeated South Africa at home. They were placed at the top of the table with 126 rating points.
India last played a Test in late December when they whitewashed Bangladesh in the away fixture. They were placed second with 115 rating points.
This meant that no other Test series was played and hence the table was not supposed to be changed, but still, India managed to find their name on the top of the charts on Tuesday afternoon, in what later turned out to be a massive blunder on the ICC website.
As per screengrabs posted by fans on social media, India retained their rating point but grabbed the top spot by virtue of Australia losing 15 points.
India will have the chance of grabbing the top spot when they face Australia at home in the four-Test Border-Gavaskar Trophy series, which begins on February 9 onwards. If India wins by a margin of 2-0 or more, they can topple Australia.
