The Stormers are sweating on the fitness of scrumhalf Herschel Jantjies and loose forward Juarno "Trokkie" Augustus ahead of their clash against the Brumbies at Newlands on Saturday.
The duo underwent scans on Monday to determine the extent of knocks picked up in the 41-24 win over the Rebels in Melbourne last weekend.
Coach Robbie Fleck explains: "Herschel Jantjies has gone for a scan and hopefully he is all clear.
“He’s been outstanding, so hopefully he’s cleared and fit to play.
“His knee flared up after the game at the airport [on our way back from Australia], so we're just doing precautionary things at the moment.
“And then Juarno Augustus has also gone for a check-up on his bicep.”
No.8 Jaco Coetzee, meanwhile, has been ruled out for a few weeks after suffering a knee injury against the Rebels.
Of Coetzee, Fleck says: “He’s got a contusion on his patella (bruised kneecap).
“It’s not as bad as we originally thought.
“Firstly they thought he might have broken his patella.
“Hopefully he will be back in the mix in the next two to three weeks.”
It wasn’t all doom and gloom for the Stormers on the injury front, with Sikhumbuzo Notshe and EW Viljoen both returning from their respective injuries.
Both of them will play for the Western Province side first, before coming into the reckoning for a place in the Stormers side.
On top of that, Fleck also welcomed back captain Siya Kolisi and Pieter-Steph du Toit to training on Monday.
The Bok pair was rested for last weekend’s match in Melbourne.
And with the rookies winning their only match on tour, without the experienced players in the squad, Fleck admits it will be tough to select the team for this weekend.
He says: “That’s the trick, you want to keep the momentum and you want to keep the confidence in the group.
“With a win like that you don’t want to change much and you also want to reward guys that produced in that final game.
“We’re going to have to think carefully about it and obviously we’ve got guys like Pieter-Steph and Siya available now and obviously that will play in our minds.
“A big part of our selection will be that those guys have done exceptionally well in the last game.”
