If a fielder is injured or becomes ill during a match, a substitute is allowed to field instead of him, but the substitute cannot bowl or act as a captain. The substitute leaves the field when the injured player is fit to return. The Laws of Cricket were updated in 2017 to allow substitutes to act as wicket-keepers, a situation that first occurred when Mumbai Indians' wicket-keeper Ishan Kishan was injured in a match on 18 April 2018.
The current sponsor of the team is BYJU's. OPPO's sponsorship was to run from 2017 until 2022, but was handed over to BYJU's on 5 September 2019. Previously, the Indian team was sponsored by Star India from 2014 to 2017, Sahara India Pariwar from 2002 to 2013 and ITC Limited (with Wills and ITC Hotels brands) from 1993 to 2002. The current kit sponsor for the Indian team until September 2020 is Nike, which in 2005 acquired the rights from BCCI. The deal with Nike has been extended twice for a period of five years each time; in 2011 and 2016 respectively. Paytm acquired the title sponsorship for all matches played by the team within India in 2015 and extended the same in 2019 until 2023. Star Sports Network is the official broadcaster until 2023 for all matches the team plays in India.
Before a match begins, the team captains (who are also players) toss a coin to decide which team will bat first and so take the first innings. Innings is the term used for each phase of play in the match. In each innings, one team bats, attempting to score runs, while the other team bowls and fields the ball, attempting to restrict the scoring and dismiss the batsmen. When the first innings ends, the teams change roles; there can be two to four innings depending upon the type of match. A match with four scheduled innings is played over three to five days; a match with two scheduled innings is usually completed in a single day. During an innings, all eleven members of the fielding team take the field, but usually only two members of the batting team are on the field at any given time. The exception to this is if a batsman has any type of illness or injury restricting his or her ability to run, in this case the batsman is allowed "A Runner" who can run between the wickets when the batsman hits a scoring run or runs. The order of batsmen is usually announced just before the match, but it can be varied.
Ganguly became the regular captain of the team in both Tests and ODIs in 2000. He remained captain until 2005–06 and became the then most successful Indian captain, winning 21 of his 49 Test matches in charge and 76 of his 146 ODIs. Under his captaincy, India became the joint-winners of the 2002 ICC Champions Trophy with Sri Lanka, and the runners-up of the 2003 Cricket World Cup. India lost only three Tests at home under Ganguly and managed to draw Test series in England and Australia. Rahul Dravid took over as Test captain in 2005. In 2006, he led India to its first Test series victory in the West Indies in more than 30 years.
