Sri Lanka's thoughts will inevitably be with absent team-mate Shaminda Eranga, as well as the task in hand at Trent Bridge, when they begin the Royal London Series against England.
Eranga is still in Dublin undergoing tests to identify the cause of the raised heart-beat which prevented him bowling in Saturday's second one-day international against Ireland.
Angelo Mathews' team have had to return to England without him to begin a five-match series for which Eranga would have been unavailable in any case after the International Cricket Council ruled he needs remedial work on an illegal bowling action.
The 29-year-old has therefore endured an especially stressful past two weeks, since his action was first called into question before the final Investec Test at Lord's.
Sri Lanka captain Mathews was the first to speak to Eranga, after he began to feel unwell at the weekend in warm-ups between innings against Ireland.
The circumstances were uncannily similar to those in which former England batsman James Taylor discovered his career-ending heart condition at the start of this summer.
There are no indications yet that Eranga's problem is so severe, although he and Sri Lanka are anxiously awaiting a diagnosis.
Mathews said: "He was warming up - and just before we went on the field, he said 'something happened to me, can you touch my heart because it is beating fast?'.
"I felt something unusual, so I quickly called the physio (who) went for the doctor with him. It was a shocking incident."
Eranga's enforced lay-off because of an illegal action was confirmed by the world governing body on Sunday lunchtime.
Mathews added: "It has been a tough 48 hours for him, and the whole team is behind him and fully supportive of him.
"We rushed him to the hospital and are yet to receive the latest news from the doctors.
"We are very confident he will come through both - his condition as well as his action.
"He will have to go back and work with the fast-bowling coaches and come back strong."
Without him, Sri Lanka are out to prove more of a match for England with a white ball than they were in a 2-0 Test series defeat.
On their last tour two years ago, they followed a surprise Test victory with success too in the ODIs - in a series notable for a furore in the final match at Edgbaston where Jos Buttler was run out at the non-striker's end after Sri Lanka twice warned him for moving out of his ground backing up.
Mathews does not regret the controversial incident, and sounds prepared to do the same again if it were necessary.
"We will play our cricket within the rules," he said.
"If someone is trying to take advantage of the rules then we will probably warn him.
"But the Test series [this year] was played in very good spirit, so I hope we'll play the ODI series in very good spirit too."
The circumstances of Buttler's 2014 dismissal were an early indication of Mathews' mettle as captain.
"You face challenging moments in life," said the all-rounder.
"Being in the hot seat is not easy, (and) sometimes you have to make those hard decisions.
"I still stand by it, because we warned him twice before. That's all we could possibly do at that time."
