Western Australia and Tasmania cricketers walked back to the pavilion a little early than the scheduled time for lunch. As per the reports of Cricket.com.au, the reason was fire. On-field umpire spotted the fire and signaled the delivery a dead ball after Australia Test pacer Jackson Bird delivered the penultimate ball of the 26th over.
The players were taken off five minutes before the scheduled time of the first session. The second session resumed on time after the officials took care of the fire. "Fire services are on-site and have assessed the situation. Players have been allowed back into the Pavilion for lunch. Play resumed at 1.10 pm local time after the lunch break," read a statement from the WACA.
There have been bizarre reasons for a play's interruption. Streakers, animals and even bee have often entered the ground to stop the action. In the ongoing Sheffield Shield encounter, Steve Smith is playing and was dismissed on a duck.
