The ICC have approved an extension of the concussion substitute rule to cover those displaying symptoms of Covid-19 in Test cricket, though not in ODIs and T20Is.
The move is part of a raft of regulation changes to prevent the spread of the novel coronavirus when cricket resumes.
As with players concussed during an international match, the match referee will approve a like-for-like replacement for any player who has to leave the field. The extension does not cover non-concussion injuries for which players have to leave the bio-secure environment for hospital scans and treatment.
Other regulation changes approved are in line with those announced after the conclusion of a recent meeting of the ICC cricket committee. There will be a ban on applying saliva on the ball, with teams receiving two warnings per innings before copping a five-run penalty if caught infringing.
Non-neutral umpires will once again be allowed to reduce the need for international travel, with teams awarded one extra DRS review per innings in each format to compensate for the fact that less experienced umpires may have to be pressed into service.
The clothing regulations will also be relaxed, with Test kits permitted to display a logo on the chest, as is already permitted in ODIs and T20Is.
