Cape Town - Siya and Rachel Kolisi have welcomed their second newborn baby into the world.
Siya, who has been ever-present for the Springboks this year and has moved into the role of vice-captain, missed Saturday's 35-6 win against Italy as he returned to cape Town to be by his wife's side.
Rachel took to Instagram on Monday to post a pic of her newborn with the words "good morning" in her caption.
Siya, meanwhile, has jetted off to Wales where he will rejoin the Boks ahead of their fourth and final Test of their end-of-year tour at the Principality Stadium on Saturday.
The Stormers loose forward has been capped 27 times by the Boks since making his debut against Scotland back in 2013.
The Boks have beaten France and Italy on tour after they were hammered 38-3 by Ireland in their opening match.
Saturday's clash against Wales kicks off at 16:30 (SA time).
