Sehwag's decision comes only two days after one of his contemporaries Zaheer Khan decided to call time on his career.
A day before his 37th birthday, Sehwag was today unveiled at the launch ceremony of the veterans 2020 league in Dubai.
When Sehwag, who was present alongside Brian Lara, Graeme Smith and Azhar Mahmood at the launch, was asked how he could play as MCL is a retired cricketers' league, Sehwag said "If I am not retired I will not play. I will go back to India and announce my retirement."
In a glorious international career spanning over 12 years, Sehwag played 104 Tests scoring 8586 runs at an impressive average of 49.34, hitting 23 centuries and 32 half-centuries.
