In the recent Test series between England and India, serious injuries were sustained by two players during a match that prevented their ongoing full contribution. Consequently, discussions have reopened relating to the introduction of full like-for-like substitutes in the game’s longest format. During its historical development, first-class cricket has flirted with substitution from time to time. An early example of substitution occurred in 1843. Thomas Barker of Nottinghamshire broke his leg while getting out of a horse-drawn carriage before a match against Hampshire at Southampton.
