Springbok flanker Schalk Burger has been ruled out of Super Rugby until after the break for the June Internationals which means he will miss the three match tour by England.
Burger tore medial ligaments in the opening round of Super Rugby and has not played since that first match back in February.
Regular Stormers captain Burger missed the Stormers' recently-completed four-week tour but had hoped to return for the opening Test against England on June the 9th.
The Stormers have however revealed that they do not expect twenty-nine-year-old Burger to recover in time for the upcoming internationals.
"Schalk Burger, Duane Vermeulen and Nick Koster (all knee injuries) are expected to return only after the June break," a statement on the club's website said.
Vermeulen's exclusion also comes as a blow to the Springboks after the No 8 enjoyed a good start to the season before also succumbing to a knee injury.
