Sonny Bill is heading to South Africa!

Cape Town - All Blacks centre Sonny Bill Williams has been declared fit and included in the Blues' 25-man squad for their trip to South Africa.

Williams suffered from concussion in the Blues' victory over the Waratahs in Sydney which ruled him out of their win over the Cheetahs in Auckland on Friday.

Blues head coach Tana Umaga has said he expects Williams to recover in time for next Friday's clash with the Stormers in Cape Town.

Kick-off is at 19:00.

However, two players who sustained injuries against the Cheetahs were not included in the Blues' touring squad.

Prop Pauliasi Manu was forced off the field with a calf injury early in the first half while Ihaia West injured his ankle when he came on in the second half as a replacement for Piers Francis.

Manu has been replaced by Sione Mafileo while Bryn Gatland comes into the squad as West's replacement.
