Jofra Archer has indicated he may pull out of this winter's Big Bash League in Australia, after acknowledging that the "mental challenge" of life in England's bio-secure bubble may, at times, have had a compromising effect on his performances.
Archer, the player of the match on Sunday as England levelled the ODI series against Australia, has spent longer in the bubble - 87 days, in all - than any other player this summer.
In that time, he had a four-day rest period between the two Test series and a further five days during the T20I series against Pakistan, but he was also required to spend a week in isolation in his hotel room at Emirates Old Trafford following an unauthorised visit to his home in Brighton after the first Test against West Indies.
While he did, at times, bowl unusually quickly in the Tests against West Indies and Pakistan, he wasn't quite able to make the same impact as he has regularly when performing for England's white-ball teams.
The amount of overs bowled in each format is one obvious explanation. Archer has bowled at least 39 overs in six of the 11 Tests he has played and makes the reasonable observation that he cannot sustain the pace over that number of overs that he can over four or 10. Equally, in white-ball cricket Archer is given a new ball and entrusted with bowling at key moments throughout the innings; in Test cricket this year, he has generally had to be content with playing a supporting role to James Anderson and Stuart Broad.
But alongside that, Archer has also acknowledged that "a change of scenery or a change of personnel" may have refreshed him ahead of the white-ball matches after admitting he felt as if he had "hit a wall" at times during the summer.
Numerous players, from relatively inexperienced ones such as Ollie Pope to vastly experienced ones like James Anderson, have described the challenges of living in the bubble for an extended period of time. The proximity to the pitch - most players have rooms looking out onto the playing surface - has, they have said, made it hard to switch off from the game and resulted in increased anxiety and weariness.
"I'll tell you, it has been mentally challenging," Archer said. "We've been in here for 16 weeks or something like that. I think it is going to be more rare going home or being normal again. Here has become the new norm. We'll just have to adjust again when we get some time off.
"The time I spend bowling with the white ball is a lot less than in Test cricket. You can't run in the whole day. It is actually impossible to run in the whole day bowling at 90mph. If you can show me someone who does it then fair play. I've not seen any bowler who bowls 90mph do it for a whole day.
"It might be different environments as well. A change of scenery or a change of personnel. You do sometimes feel like you hit a wall. Sometimes you just need to relax or just need to switch your mind off for a few days.
"I honestly don't know what it is but if you're in a good frame of mind I feel you'll probably bowl a bit faster. On Sunday, I didn't feel as though I was bowling that fast. At times I felt I've bowled faster. For me as long as I feel good, I don't care what speed I'm bowling at."
For Archer, at least, the bubble life looks set to continue for a while yet. Along with the other England and Australia players contracted to IPL teams, he will fly to the UAE on Thursday - the day after the final ODI of the summer - on a specially charted flight. From there, he could be facing more time in lockdown if England, as planned, visit South Africa for a limited-overs tour in November and then visit India - or the UAE - for an all-format tour in the new year. There is every chance the 2021 English season may have to be played in similar conditions, too.
As a result, he has confirmed he does not anticipate taking part in the BBL this year and indicated a hope to take some time off before Christmas.
"I'll be honest with you. I'm not sure how many more bubbles I've got left in me for the rest of the year," Archer continued. "I haven't seen my family really since February and it's September now. The IPL is going to take up most of October. In November we go to South Africa; well, hopefully we go to South Africa. That only leaves me with a few weeks in December for the rest of the year.
"I love my Hobart [BBL] family but I think I need to spend some time with my real family as well. When the year turns, we're going to be back in a bubble in the UAE and India or somewhere. Family time is really important especially when you're in the bubble and you can't see them physically. So any time I get I try to spend with them."
