Sachin Tendulkar was always seen with his No. 10 jersey on the field. The jersey will not be worn for international matches as the Board of Control for Cricket in India (BCCI) decided to retire the same unofficially.
India Today informed that the little master wore the famous No. 10 jersey during the ODI match against Pakistan in March 2012. He was seen with it during one day and T20 international matches.
Times Now mentioned that this sudden decision was made after the social media trolls that did the rounds when player Shardul Thakur wore it during his debut match against Sri Lanka. The new player was trolled by people in social media, including cricket players like Rohit Sharma. Thakur informed that he chose the same since it was based on his birth date. Harbhajan Singh spoke in favor of the young cricketer. He also suggested that it could have been a way to acknowledge the immense contribution of the master blaster to cricket.
A BCCI official said that ICC does not allow retiring a jersey. It is however not mandatory to wear any given number. Retiring it unofficially seems to be a way out to avoid unnecessary criticism of players through social media. It can, however, be worn during a non-international A list match.
