In a welcome move, the Marylebone Cricket Club (MCC) on Thursday made concussion replacements available in English county cricket for the first time since its inception.
"This is a change made in the interests of player safety and health," the England and Wales Cricket Board's (ECB) chief medical officer Dr Nick Peirce was quoted as saying by BBC.
"While concussion is not as common in cricket as in contact sports such as rugby, our research has shown an average of around 15-20 incidents in first and second team cricket during each of the last few seasons," he added.
It has to be a "like for like" replacement overseen by match officials. The new rule will apply in the County Championship, One-Day Cup, T20 Blast and Women's Super League.
