Western Province's opening batter Joshua van Heerden has been the first like-for-like injury replacement. Van Heerden replaced Edward Moore in a CSA 4-Day Series Division 1 match against Lions and became the first-ever substitute under the new trial for substitutes in cricket. Van Heerden tore his left adductor (inner thigh muscle) while fielding on Day 2 of the match at Newlands in Cape Town. On the other hand, the trial of substitutes in a new trial is a part of an effort initiated by the International Cricket Council (ICC) and is also underway in Australia (Sheffield Shield) and India (Ranji Trophy and Duleep Trophy). The law is inspired by finding a remedy for sides losing players due to serious injuries during a multi-day match. Similar to the course of action that Australia is taking, South Africa is mulling internal and external injuries in the event of replacing players. India, on the other hand, have only taken note of external injuries until now.

Subsequently, the report is forwarded to CSA's chief medical officer Dr Hashendra Ramjee and CSA's cricket operations manager Obakeng Sepeng, who have both been tasked with reading the results. The two then have the responsibility of contacting the match referee requesting confirmation. Alternatively, if the injury is an external one, for example, a visible dislocation or fracture, the match referee may him/herself decide on the substitution after taking advice from Dr Ramjee and Sepeng. We can see variances in the protocols adopted by various countries. This is due to various boards desiring to utilize the system differently. All of the cricket boards will ultimately report back to the ICC with the trial findings. It is a long shot that the ICC introduces the like-for-like substitutions rule to the international game. Currently, concussion substitutes are all they use.
