Jason Roy has explained his light-headedness during England's one-day international win over Pakistan was due to low blood sugar levels.
The opener hit 65 from 56 balls to earn the man of the match award as England won by 44 runs on the Duckworth-Lewis method to take a 1-0 lead in the five-match series.
After Pakistan set a below-par 260-6, the hosts were well ahead of the rate at 194-3 with more than 15 overs remaining when rain curtailed proceedings at the Ageas Bowl.
There was a moment of concern for Roy midway through his innings when he received treatment after suffering a dizzy spell, but he insisted it was nothing to worry about.
"It was a case of not having enough sugar on me apparently, that's it plain and simple," he said.
"I had a headache, felt a bit dizzy, they got the physio and the doctor on, they told me to get some sugar on board. I'll just remember in future on a hot day to be mindful of that.
"I was able to get my bearings, settle and reset myself and just go again."
