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 team is considered a strong but unpredictable team. Traditionally Pakistani cricket has been composed of talented players but is alleged to display limited discipline on occasion, making their performance inconsistent at times. In particular, the India-Pakistan cricket rivalry is usually emotionally charged and can provide for intriguing contests, as talented teams and players from both sides of the border seek to elevate their game to new levels. Pakistan team contests with India in the Cricket World Cup have resulted in packed stadiums and highly charged atmospheres. The team is well supported at home and abroad, especially in the United Kingdom where British Pakistanis have formed a fan-club called the "Stani Army". Members of the club show up to matches across the country and are known to provide raucous support. The Stani Army also takes part in charity initiatives for underprivileged Pakistanis, including annual friendly cricket matches against British Indian members of the similar "Bharat Army".
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.
The 1970s, for the England team, can be largely split into three parts. Early in the decade, Illingworth's side dominated world cricket, winning the Ashes away in 1971 and then retaining them at home in 1972. The same side beat Pakistan at home in 1971 and played by far the better cricket against India that season. However, England were largely helped by the rain to sneak the Pakistan series 1–0 but the same rain saved India twice and one England collapse saw them lose to India. This was, however, one of (if not the) strongest England team ever with the likes of Illingworth, Geoffrey Boycott, John Edrich, Basil D'Oliveira, Dennis Amiss, Alan Knott, John Snow and Derek Underwood at its core.
