Teams will be allowed two extra reviews per innings in Test matches as part of a trial set up by the International Cricket Council starting next month.

The ICC says a team’s referral count, currently set at two, will be topped up to two reviews after 80 overs of an innings in matches where DRS is used.

The trial starts on October 1, meaning it should be in operation for the Ashes series which begins in Brisbane on November 21.

The use of DRS was one of the key issues discussed at a two-day meeting of the ICC chief executives’ committee in Dubai, in the wake of the recent Ashes series in England that was blighted by contentious umpiring decisions.

The ICC will set up a working group to consider the role of technology in umpire decision-making, and announced it will clamp down on slow over-rates.
