Gary Ballance is set to make his Yorkshire return as a batsman only in Sunday’s Royal London One-Day Cup match against Leicestershire.
The 28-year-old batsman, who has 23 Test caps for England, was granted time off by Yorkshire for personal reasons last week.
Martyn Moxon, the Yorkshire director of cricket, told The Yorkshire Post: “It’s difficult to give a specific reason [for Ballance’s absence], other than the fact that he’s just felt unwell.
“It’s hard. Nobody can really define exactly what it is. He’s just not felt well. He’s been feeling tired and off it and just lifeless. There’s no kind of specific illness as such.
“But he’s had some time away and had a bit of a rest and slept better. It’s kind of like a fatigue-type thing, but there’s no terminology that we’ve been given that it’s this or it’s that. It’s basically just the way he’s been feeling.”
Ballance pulled out of the County Championship match against Surrey at The Oval two weeks ago, since when he has missed half of the club’s Royal London One-Day Cup campaign.
His return would clearly boost a Yorkshire side who have won just one of their opening four One-Day Cup matches.
Bowler Steven Patterson took over as captain and will continue in the role for the rest of the one-day competition.
“I’ll keep doing it until I’m told Gary is ready and then move aside,” said Patterson.
