The Blues have lost their third straight Super Rugby game after the Cheetahs kicked a last-minute penalty to win 25-24 in Bloemfontein on Saturday morning.
Cheetahs first five eighth Joe Pietersen booted the late penalty as the South Africans snatched the last-gasp victory at the Free State Stadium, their second win from two games this season after last weekend's bye.

Pietersen kicked two conversions and two penalties, including his last-minute effort after the Blues had infringed at a lineout.
