South Africa and New Zealand both announced injury setbacks on Thursday ahead of two Tests between the countries starting on January 2.
South African fast bowler Vernon Philander suffered a hamstring injury during a domestic four-day match in Cape Town on Thursday and will not bowl again for the Cape Cobras against the Titans.
Team manager and doctor Mohammed Moosajee said it was a grade one injury to his left hamstring and the normal recovery period was ten to 14 days. This could make Philander a doubtful starter for the first Test in Cape Town.
New Zealand, meanwhile, will be without leading fast bowler Tim Southee for the two-Test series after Southee injured a thumb during a domestic match between Northern Districts and Wellington.
Neither Philander nor Southee was due to play in a three-match Twenty20 series which starts in Durban on Friday.
