The Stormers expect talismanic centre Jean de Villiers to be fit for this weekend's Super Rugby clash against the Bulls.
De Villiers has been sidelined with a sternum injury sustained whilst captaining South Africa during the June Test series against Scotland, Italy and Samoa.
However he is now set to return to action this weekend at Newlands, although full-back Joe Pietersen is a major doubt.
In the event of Pietersen missing the match due to a major bruise on his leg, Coetzee stated the Stormers would turn to Gio Aplon rather than highly-rated youngster Cheslin Kolbe in the 15 jersey.
"Jean will be back, he is looking good for this weekend," said Coetzee.
"Joe Pietersen has a severe hematoma on his quad and we will give him until Wednesday and see how he goes.
"We have got Cheslin here, but it would be silly just to chuck him in. I think Gio Aplon has done duty for us there before and Gerhard van den Heever also performed very well this last weekend.
"There will be plenty of time for Cheslin to come through in the Currie Cup, you want to set him up to utilise his expertise by making sure he knows the systems."
