Sunwolves trio return for Cheetahs
Seasoned centre Derek Carpenter, one of the stalwarts of the team, lock Kotaro Yatabe and hooker Yusuke Niwai all return from a conditioning lay-off for the encounter with the visiting South African franchise.
Coach Filo Tiatia said it is important to get a win, as this is their last match before the June international break.
"We played reasonable well for an hour against the Sharks in Singapore last week," Tiatia said, adding: "We leaked three tries [in the final quarter].
"We have to improve and ensure it reflects in the result."
He said they will expect the Cheetahs to maul a lot.
"They have a good set piece and they are going to take us on up front."
