England seamer David Willey will be unable to bowl for the next six weeks after suffering an abdominal injury.
Willey's new club Yorkshire revealed their winter signing has hurt his side and faces a spell out of action.
The 26-year-old has made great strides for England's limited-overs teams, including on the way to last month's final of the ICC World Twenty20.
But in only his second match for Yorkshire since his move from Northamptonshire, injury has struck and may put the 26-year-old in doubt for the Royal London Series against Sri Lanka, which follows three upcoming Test matches, and begins on June 21.
Yorkshire tweeted: "@david_willey diagnosed with abdominal injury, ruling him out of bowling action for 6 weeks."
The bowling all-rounder may be allowed to bat if required on the final day of Yorkshire's Specsavers County Championship Division One match at home to Surrey.
England, meanwhile, have two left-arm seamers on the sidelines - after Willey's fellow World Twenty20 squad member Reece Topley broke his right hand on his Hampshire debut last month.
