All Black Tamati Ellison and foundation Rebel Laurie Weeks will undergo tests this week ahead of a projected return, in a boost to the Rebels ahead of the trip to Canberra to face the Brumbies on Saturday.
The duo, who missed the game against the Waratahs with a minor knee and ankle injury respectively, would provide some extra experience to the squad.
"Tamati and Laurie were both very close to playing against the Waratahs," Rebels' Head of Athletic Performance Bryce Cavanagh said.
"We gave them every chance to get up, and they fell just short. Again, we'll give them every chance this week; we're confident that both will travel to Canberra and play."
Backrower Lopeti Timani's unlucky run with injuries continues, after hurting himself in the Dewar Shield on the weekend.
"Lopeti suffered an ankle injury playing Club Rugby on the weekend, and we will know the full extent (of the injury) later this week," Cavanagah said.
"It's the same injury suffered by Nic Stirzaker, and a real shame for him. He has worked very hard this year, however a number of 'unpreventable' injuries he has picked up have prevented him from being in a position to push for a consistent spot in the matchday 23."
Those in the rehabilitation squad are continuing under the wachful eye of the Club's medical and rehabilitation stff, and Cavanagh has seen some positives in their progress.
"Luke Burgess and Nic Stirzaker are working hard rehabilitating, and are pushing to be back for the last home game of the season against the Queensland Reds.
Lachlan Mitchell remains a while off yet, while Tom Sexton still looks to be on target to play in the National Rugby Championship (NRC), which would be a great way for him to get used to Australian Rugby."
Three players this week depart on internationl duty, however two return after playing for their country over the last fortnight.
"Sean McMahon and Lalakai Foketi are unavailable for selection, in New Zealand with the Australian U20s side, while prop Eddie Aholelei is on international duty with Tonga. We are pleased to welcome Shota Horie and Male Sau back into contention however, after both played key roles in Japan's success in securing 2015 Rugby World Cup qualification on the weekend.
"They have headed straight back to Melbourne to resume training with the squad, and these guys are both consummate professionals; we know that they will work hard to be ready to jump straight back into contention."
