Australia pace spearhead Mitchell Starc has become the latest cricketer to raise concerns over the mental well-being of players staying in a bio-bubble as he feels it is “not sustainable” to live in such restrictions for a prolonged period.

“It’s not a sustainable lifestyle,” Starc was quoted as saying by cricket.com.au.

“You’re living in a hotel room with zero outside contact. Some guys haven’t seen families or their kids for a long time, those guys in the IPL.”

“It’s tough going — we get to play cricket, (so) we can’t complain too much — but in terms of well-being of players, staff and officials, for how long can you stay in hubs?” Starc questioned the model.

“That question remains to be answered... For those guys who have been in the IPL and have to turn around and do another IPL at the end of next summer (in April and May 2021), they’re earning their money.”

India captain Virat Kohli had recently said that the “repetitive” nature of being in a bio-bubble can be mentally challenging and the length of tours will have to be considered accordingly if playing in such an environment becomes the norm.
