Cape Town - Brumbies loose forward David Pocock has been named in coach Stephen Larkham's side for Saturday's playoff against the Stormers at Newlands, but reports suggest that his condition will be monitored up until kickoff.
The Stormers, meanwhile, were sweating over the availability of Schalk Burger after the flank picked up a groin injury at training on Thursday.

Pocock was due to undergo more concussion tests on Friday.
The Wallaby veteran left the field last weekend against the Crusaders with concussion, and Larkham confirmed this week that the player was 'on track' to play against the South African conference champions.
But Stormers coach Allister Coetzee is not spending any time thinking about Pocock's recovery, and was quick to point out that the Brumbies forwards threat is about more than one player.
"If he's not playing they will still have a fantastic back three," said Coetzee.
"(Jarrad) Butler is a fantastic player... when he came on against the Crusaders he scored two tries in the end, effectively.
"It is very similar to their squad mentality - whoever comes in settles in nicely. If Pocock is not playing then Butler will definitely do that job of a poacher and as a runner and the guy at the back of driving mauls that can finish a job."
Coetzee again expected the battle for ball to have a major say in Saturday's outcome, as was the case when the sides met last month in a league match.
"It's a difficult team to play. They're hard at the breakdown, they will do whatever they can to slow our ball down and so that's where the contest will be," he said.
"For us we understand that we won't get ball on a platter, we've got to earn and work hard for that. They're a team with a massive work-rate.
"The Brumbies don't play rugby in their half - they simply don't. They're a distance kicking side and they want you to play and make mistakes and we understand that.
"They will also be testing and putting balls behind us, try and pin maybe Cheslin (Kolbe) and the wingers down. But we've worked out plans and hopefully we're really accurate with our plans and when we get it right there will be lots of opportunities."
Kick-off on Saturday is at 17:05.
