The Ian Foster coached Chiefs side have suffered a huge blow as they prepare to leave for Pretoria today after All Black winger Sitiveni Sivivatu has been ruled out of the Super 14 finals this weekend.

Sivivatu suffered a shoulder injury during the second half of their 14-10 semifinal win over the Hurricanes on Friday night.

The side which leaves for South Africa tomorrow morning will see Waikato midfielder Jackson Willison replace the Fijian.

On a positive note, All Blacks centre Richard Kahui has been named despite a bruised calf saw him sit out the semifinal on Friday.

Some notable faces in the 24 member squad that has been named to leave for South Africa tomorrow are Sione Lauaki, Liam Messam, Mils Muliaina, Leila Masaga and Dwane Sweeney.

The Bulls take on the Chiefs on Sunday at 3.30am in Pretoria.
