Hawthorn's match-winning forward/midfielder Cyril Rioli is expected to miss two or three AFL matches with bone bruising to his shoulder, the Hawks said on Monday.
Rioli was subbed off at halftime during Sunday's round-20 game in Launceston against Port Adelaide.
Scans have revealed bone bruising to the scapula and deep muscle bleeding around the nerve.
"We will be in better position to determine a timeline for Cyril's return when the injury site has settled and he resumes training," Hawthorn football operations manager Mark Evans said.
Rioli's fellow premiership forward Lance Franklin is rated a good chance to return on Sunday against Gold Coast at the MCG after missing five matches with a hamstring injury.
"They're just being pretty cautious with him (Franklin), but I think you'll see him back out there this week," vice-captain Jordan Lewis said.
Leading commentator and medical expert Dr Peter Larkins queried whether Franklin had suffered a setback during his recovery.
"They've said no recurrence (of the injury). They're just being conservative," Larkins told Radio 3AW.
"Is it going to take five weeks to get over what he had? I would have said no.
"When a player misses this much, I normally think they've had a recurrence."
The fourth-placed Hawks say defender Josh Gibson has been cleared of any major damage to his ankle.
Key forward Jarryd Roughead is likely to return after being rested with an ankle injury last weekend.
