Gold Coast hope captain Gary Ablett will not join fellow midfielder Michael Rischitelli as a long-term AFL casualty.
Scans on Monday are expected to confirm that Rischitelli needs a knee reconstruction, putting him out of action until well into next season.
Rischitelli hurt his right knee in the first term of Saturday's QClash win over Brisbane.
He was on crutches post-match and the Suns are not confident about the prognosis.
But they are hopeful that Ablett has not done serious damage to his left shoulder.
It is the same shoulder that needed a reconstruction two years ago.
The two-time Brownlow Medallist was hurt when he tried to tackle Mitch Robinson and he left the field in the last quarter.
Suns coach Rodney Eade said after Saturday's win there were signs that the incident had not done serious damage.
Like Rischitelli, Albett will undergo scans on Monday.
Dion Prestia (knee) is also in doubt for Saturday's Cairns match against the Western Bulldogs, who have their own injury worry from the weekend.
Midfielder Tom Liberatore was taken to hospital during Saturday night's win over Richmond with rib damage.
He was cleared of internal injuries, but is in doubt for next weekend.
And North Melbourne are unsure whether injured stars Daniel Wells and Jarrad Waite will return for Saturday's must-win game against Port Adelaide at Etihad Stadium.
The Kangaroos also lost Mason Wood (knee) and Farren Ray (hamstring) during Sunday's loss to West Coast, while Nick Dal Santo was a late withdrawal because of illness.
