Waratahs coach Michael Foley looks set to rotate several of his forwards with Dave Dennis and Sitaleki Timani in line to return to the starting line up for this week's crucial match.
The Waratahs play the Stormers this weekend in a match that they have to win if they want to stay in line for the play offs.
Daniel Halangahu could also be dropped for Bernard Foley at fullback but the selectors are expected to persevere with the Adam Ashley-Cooper and Rob Horne centre combination
Waratahs coach Michael Foley says that while his full squad was available for this week's match the tough Super Rugby schedule makes it imperative that a number of forwards get rest.
"There are a couple of blokes we're having a look at, because in the scrum, there have been some guys who've put a lot of miles on the clock, and it may be time to rest some of them," Foley said.
"There was a six-day turnaround between the Brumbies and Bulls games, followed by a long flight."
"We always knew this would a challenging point in the season, so we've had to take note of how guys have pulled up after the Bulls game."
Foley's mosty likely changes are returning Dennis back to the back row and bringing Timani to the second row which means that even though Rocky Elsom was a standout play against the Bulls he could be dropped to the bench.
Wallabies winger Drew Mitchell has been named in the travelling squad but is more likely to be named next weekend against the Cheetahs in Bloemfontein.
"Drew's looking good for next week. Everything is on course. We brought him to South Africa on the proviso that he would be ready to play for the Cheetahs game."
"And at this point in time he is available," Foley told the Sydney Morning Herald.
