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.
A bowler reaches his delivery stride by means of a "run-up" and an over is deemed to have begun when the bowler starts his run-up for the first delivery of that over, the ball then being "in play". Fast bowlers, needing momentum, take a lengthy run up while bowlers with a slow delivery take no more than a couple of steps before bowling. The fastest bowlers can deliver the ball at a speed of over 145 kilometres per hour (90 mph) and they sometimes rely on sheer speed to try to defeat the batsman, who is forced to react very quickly. Other fast bowlers rely on a mixture of speed and guile by making the ball seam or swing (i.e. curve) in flight. This type of delivery can deceive a batsman into miscuing his shot, for example, so that the ball just touches the edge of the bat and can then be "caught behind" by the wicket-keeper or a slip fielder. At the other end of the bowling scale is the spin bowler who bowls at a relatively slow pace and relies entirely on guile to deceive the batsman. A spinner will often "buy his wicket" by "tossing one up" (in a slower, steeper parabolic path) to lure the batsman into making a poor shot. The batsman has to be very wary of such deliveries as they are often "flighted" or spun so that the ball will not behave quite as he expects and he could be "trapped" into getting himself out. In between the pacemen and the spinners are the medium paced seamers who rely on persistent accuracy to try to contain the rate of scoring and wear down the batsman's concentration.
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.
However, there are downsides to having such a cricket-loving population. Many Indians hold cricket very close to their hearts and losses are not received well by the Indian population. In some cases, particularly after losses to Pakistan or after a long string of weak performances, there have been reports of player effigies being burnt in the streets and vandalism of player homes. In many cases, players have come under intense attention from the media for negative reasons, this has been considered as one of the reasons for Sourav Ganguly being left out of the Indian team. At times, when a match is surrounded by controversy, it has resulted in a debacle. For example, when India slid to defeat against Australia at Brabourne Stadium in 1969, fans began throwing stones and bottles onto the field as well as setting fire to the stands, before laying siege to the Australian dressing rooms. During the same tour, a stampede occurred at Eden Gardens when tickets were oversold and India fell to another loss; the Australian team bus was later stoned with bricks . A similar event occurred during the 1996 Cricket World Cup, where India were losing the semi-final to Sri Lanka at Eden Gardens. In this case, the fan behaviour was directed at the Indian team in disappointment at their lacklustre performance. An armed guard had to be placed at the home of captain Mohammad Azharuddin to ensure his safety. Indian fans have also been passionate in their following of Sachin Tendulkar, who has been commonly thought of as one of the best batsmen in the world. Glorified for the bulk of his career, a riot occurred in early 1999 in a Test against Pakistan at Eden Gardens after a collision with Pakistani paceman Shoaib Akhtar saw him run out, forcing police to eject spectators and the game to be played in an empty stadium. Although in 2006, a string of low scores resulted in Tendulkar being booed by the Mumbai crowd when he got out against England
Similar to the first-class kits, BCCI logo is placed on the left chest while the logo of the kit manufacturer (Nike) sits on the right chest. The official team sponsor's logo (currently BYJU'S) is present on the central part of the jersey usually above 'INDIA' text as well as the sleeve of the players' leading arms. For T20 kits, in addition to these, the sponsor's logo is also present on the back, below the players' numbers. However, for ICC tournaments, the tournament logo is placed on the right chest and the sponsor's logo is allowed only on the sleeve of the players' leading arms. The kit manufacturer's logo in such cases will be printed on the sleeve of the players' non-leading arms. The name and jersey number of the players are printed on the back.
