Sussex have been dealt a blow with overseas player Vernon Philander ruled out of the Royal London One-Day Cup group stage.
All-rounder Philander, who is signed to the county for the first half of the 2017 season, has been sidelined with a groin injury that will also keep him out of the Specsavers County Championship clash with Nottinghamshire which starts on Friday.
Sussex had planned for Philander to play in six County Championship matches and the group stage of the One-Day Cup, which runs from April 27 to May 17.
The 31-year-old sustained the injury during Sussex's opening County Championship match against Kent at the weekend and will return home to South Africa for his rehabilitation.
A club statement read: "Sussex regret to announce that overseas player Vernon Philander will be out of action for a period of two to three weeks.
"We are pleased that he will return to Hove to be available for the remaining four County Championship matches of his agreed contract with the club, beginning with the match against Durham on Sunday, May 21, finishing in the middle of June.
"He will now however be unavailable for Sussex's Royal London One-Day Cup campaign."
Philander has featured in 43 Tests and 30 One-Day Internationals for the Proteas and has previously had spells in county cricket with Middlesex, Somerset, Kent and Nottinghamshire.
