Mason Crane is to have a scan on Monday having experienced a recurrence of pain in his back.
Crane, the 21-year-old leg-spinner who made his Test debut in the final Test of the Ashes in Sydney, was sent home within the first few days of the tour of New Zealand having been diagnosed with a partial stress fracture in his lower back. The England camp felt they had caught the problem early
He made his comeback for Hampshire a couple of weeks ago but, after seven Royal London Cup games, he felt further discomfort in his back and was not included in the side for the Championship match against Surrey which started on Saturday.
While it is understood that Hampshire and England are taking a cautious approach with Crane, there will be concern that he has experienced any further discomfort so soon and after a relatively light bowling load.
Toby Roland-Jones was also forced to miss a Test tour over the winter - he was ruled out of the Ashes due to a stress fracture - and then aborted his comeback in the early days of this season after a recurrence of the problem. He is not expected to play again this season.
