In order to attract more spectators to Test cricket, it may be reduced to four days, hinted the ICC president David Morgan.

In an attempt to make the traditional version of the game more result oriented and productive, this may be one of the steps that could be introduced amongst others like a two-tier format, day-night Test matches, etc.

"I would be very surprised if within a year you haven't seen some significant changes in Test match cricket," Morgan told an Indian News magazine.

"We are examining whether Test match can be played over four days rather than five. We need better over-rates, better pitches that give a good balance between bat and ball and we need to consider day-night Test cricket," he said.

The ICC president is also mulling on the option of the pink or an orange ball during the day-night Test matches.

"We are looking very closely at ball manufacturing design that replicates a red ball, maybe an orange ball, a ball that could still allow us to play in white clothing and still at night."
