But that’s exactly the role they will fill for the Cheetahs in their Super Rugby game against the Bulls at Loftus this weekend.
Cheetahs coach Naka Drotske named the duo among his replacements as he decided to retain the same starting line-up who outplayed the Stormers 35-22.
“We are looking at giving Coenie about 20 minutes from the bench,” remarked Drotske.
“But we have also seen what an impact our bench made for us last weekend in the final 20 to 30 minutes and we are looking at them to make the same impact.”
In a third change to the bench, Drotske has recalled lock Ligtoring Landman at the expense of Waltie Vermeulen.
A lingering groin injury has ruled flank Lappies Labuschagne out for a third consecutive week.
Meanwhile, the Stormers have dropped hooker Deon Fourie, flank Siya Kolisi, flyhalf Peter Grant and wing Devon Williams.
Fourie, Kolisi and Grant will be starting from the bench, but Williams has been dropped from the squad altogether as the Stormers aim to win only their third game of the season after victories over the Hurricanes and the Lions.
They are replaced by Scarra Ntubeni, Schalk Burger, Kurt Coleman and Sailosi Tagicakibau.
Stormers coach Allister Coetzee said the impact made by Coleman and Burger in the second half against the Cheetahs last weekend was impressive.
