Tom Curran pulls out of Big Bash over 'bubble' fatigue

England all-rounder Tom Curran has apologised to Sydney Sixers fans for withdrawing from Australia's Big Bash League after becoming fatigued with playing in biosecurity bubbles during the Covid-19 pandemic.

Curran's pull-out comes days after England teammate Tom Banton withdrew from BBL side Brisbane Heat for the domestic Twenty20 competition which starts December 10.

"I'm really sorry not to be playing in this year's Big Bash," 25-year-old Curran said in a Sixers team release on Monday.

"As you'll already know, it's been a very challenging year and I've been in (bio-security) bubbles since July.

"I will hopefully be back for many years to come, recharged and ready to go again, but for now I just need some time, normality, see family and be home."

Curran, the Sixers' top wicket-taker last season, was scheduled to join the team after Christmas after spending two weeks in quarantine upon arrival in Australia.

The Sixers said they supported Curran's decision.

"The varying conditions we are asking our players to play cricket in worldwide is taking its toll and we understand Tom's need for a break over this BBL season," Sixers General Manager Jodie Hawkins said.

Both Curran and Banton were part of England's white-ball squads before heading to the Indian Premier League in the United Arab Emirates and were in South Africa where Covid-19 outbreaks have disrupted England's tour.

A number of top cricketers have expressed concern about being confined to biosecure bubbles for months on end to keep international schedules on track.

Australia paceman Mitchell Starc said last month it was "not a sustainable lifestyle".

The pandemic and Australia's strict quarantine requirements have also forced change to the BBL's schedule, with the first tranche of matches to be played in southern Tasmania state rather than across the country as in past tournaments.
