The Queensland Reds will be waiting on scans to determine the severity of Samu Kerevi's hand injury.
Kerevi cut a forlorn figure on the Reds sideline after coming off with the injury midway through the second half of the Reds' 30-17 win over the Cheetahs.
Reds co-coach Nick Stiles said the outside centre would have scans on Sunday to diagnose the injury, which could be a broken hand.
If that is the case, Kerevi could miss a month of Super Rugby, a timeline that would keep him in the running for Test duties in June.
"With Samu, it's a suspected broken hand," Stiles said.
"That'll be scanned tomorrow and potentially if it's broken it could be three to four weeks, depending on the severity."
Captain James Slipper said the setback was a blow for Kerevi but shouldn't count out his chances of a Wallabies spot, in June or later on.
"It'd be extremely disappointing for him to miss any games," he said.
"He's been a crucial part of our team not just this year but last year as well.
"He's grown not just as a player on the field but a bloke off the field. He's one of our young leaders.
"He's got a level head on himself. I don't think he needs to be about future aspirations with the Wallabies, he just needs to be concentrating on staying fit and sorting through his injuries and playing good rugby, which he's consistently been doing.
"We all know he's a future Wallaby so he just needs to keep being consistent, stay humble and keep working hard.
"He's a great bloke and would serve this country very well."
Kerevi's injury was a sour point in an otherwise positive night for the Reds, in which a second-half effort helped them break away from the Cheetahs, in stark contrast to recent efforts.
Slipper said that was one big benefit to take out of the 30-17 win.
"We've been guilty in recent weeks of resting on our laurels a bit (but tonight) we wanted the scoreboard to keep ticking over, keep the pressure on them and execute, which I thought we did.
The Reds travel to New Zealand next weekend to face the Crusaders in what will be a major challenge for Queensland.
