Sam Billings' return to action for Kent lasted just a matter of minutes, as he suffered a dislocated shoulder that may rule him out of England's ODI trip to Ireland next week.

Billings, Kent's captain, had returned to the team for his first county fixture of the season, against Glamorgan at Cardiff in the Royal London Cup, after completing his stint with Chennai Super Kings in the IPL.

However, he suffered a dislocated left shoulder in attempting to stop a shot in Harry Podmore's first over of the match.

In obvious pain, Billings was left prone on the outfield for several minutes, and treated with oxygen before being helped from the field.

Kent later confirmed that he had been taken to hospital, where the shoulder was relocated, and returned to Sophia Gardens afterwards. He is scheduled to see a specialist on Friday, where he will undergo scans.

Billings had not been included in England's 15-man squad for next month's World Cup, but was likely to play against Ireland in Dublin next Friday, and had also been named for the one-off T20I against Pakistan in Cardiff two days later.

He is one of a number of concerns for England, particularly among their batsmen, as they build towards the World Cup opener against South Africa at The Oval on May 30.

Jason Roy is missing for Surrey in the latest round of Royal London Cup games, after suffering a back spasm earlier this week, while Eoin Morgan also sat out the same fixture for Middlesex after complaining of sore shins before the toss.

Kent's other England selection, Joe Denly, was not included for the trip to Glamorgan after himself suffering a back spasm while batting against Gloucestershire on Tuesday.

Alex Hales, meanwhile, has been put on indefinite leave by Nottinghamshire for personal reasons, but is expected to link up with the England squad for a pre-season training camp in Cardiff this weekend.
