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.
At the end of the 2004 season, India suffered from lack of form and fitness from its older players. A defeat in a following home Test series against Australia was followed by an ODI home series defeat against Pakistan followed by a Test series levelled 1–1. Greg Chappell took over from John Wright as the coach of the Indian cricket team following the series, and his methods proved to be controversial during the beginning of his tenure. The tension resulted in a fallout between Chappell and Ganguly, resulting in Rahul Dravid being made captain. This triggered a revival in the team's fortunes, following the emergence of players like Mahendra Singh Dhoni, Suresh Raina, and the coming of age of players like Irfan Pathan and Yuvraj Singh. A thumping home series victory over Sri Lanka in 2005 and a drawn series with South Africa put India at second place in the ICC ODI rankings. Dravid, Tendulkar and Virender Sehwag were selected to play for the ICC World XI in the 2005 "SuperTest" against Australia. A convincing ODI series win in Pakistan in early 2006, following a loss in the Test series, gave India the world record of 17 successive ODI victories while batting second. Towards the middle of 2006, however, a 4–1 series loss in the West Indies gave rise to a slump in India's ODI form, while they achieved a 1–0 victory in the Test series that followed, giving them their first Test series victory in the Caribbean since 1971. India's ODI form slumped further with a disappointing performance in the 2006 Champions Trophy and a drubbing in the ODI series in South Africa. This was followed yet again by an initial good performance in the Tests, giving India its first Test match win in South Africa, although they went on to lose the series 2–1. This Test series was marked by Ganguly's comeback to the Indian team.
The game underwent major development in the 18th century to become England's national sport. Its success was underwritten by the twin necessities of patronage and betting. Cricket was prominent in London as early as 1707 and, in the middle years of the century, large crowds flocked to matches on the Artillery Ground in Finsbury. The single wicket form of the sport attracted huge crowds and wagers to match, its popularity peaking in the 1748 season. Bowling underwent an evolution around 1760 when bowlers began to pitch the ball instead of rolling or skimming it towards the batsman. This caused a revolution in bat design because, to deal with the bouncing ball, it was necessary to introduce the modern straight bat in place of the old "hockey stick" shape.
The inter-war years were dominated by Australia's Don Bradman, statistically the greatest Test batsman of all time. Test cricket continued to expand during the 20th century with the addition of the West Indies (1928), New Zealand (1930) and India (1932) before the Second World War and then Pakistan (1952), Sri Lanka (1982), Zimbabwe (1992), Bangladesh (2000), Ireland and Afghanistan (both 2018) in the post-war period. South Africa was banned from international cricket from 1970 to 1992 as part of the apartheid boycott.
According to the social historian Derek Birley, there was a "great upsurge of sport after the Restoration" in 1660. Gambling on sport became a problem significant enough for Parliament to pass the 1664 Gambling Act, limiting stakes to £100 which was, in any case, a colossal sum exceeding the annual income of 99% of the population. Along with prizefighting, horse racing and blood sports, cricket was perceived to be a gambling sport. Rich patrons made matches for high stakes, forming teams in which they engaged the first professional players. By the end of the century, cricket had developed into a major sport which was spreading throughout England and was already being taken abroad by English mariners and colonisers – the earliest reference to cricket overseas is dated 1676. A 1697 newspaper report survives of "a great cricket match" played in Sussex "for fifty guineas apiece" – this is the earliest known match that is generally considered top-class.
In a two-innings-a-side match, one team's combined first and second innings total may be less than the other side's first innings total. The team with the greater score is then said to have "won by an innings and n runs", and does not need to bat again: n is the difference between the two teams' aggregate scores. If the team batting last is all out, and both sides have scored the same number of runs, then the match is a tie; this result is quite rare in matches of two innings a side with only 62 happening in first-class matches from the earliest known instance in 1741 until January 2017. In the traditional form of the game, if the time allotted for the match expires before either side can win, then the game is declared a draw.
In the approximate centre of the field is a rectangular pitch (see image, below) on which a wooden target called a wicket is sited at each end; the wickets are placed 22 yards (20 m) apart. The pitch is a flat surface 3 metres (9.8 ft) wide, with very short grass that tends to be worn away as the game progresses (cricket can also be played on artificial surfaces, notably matting). Each wicket is made of three wooden stumps topped by two bails.
