Brisbane have suffered a scare in the lead-in to the NRL grand final, with centre Herbie Farnworth leaving training early, and star fullback Reece Walsh and captain Adam Reynolds both receiving treatment for left leg niggles.
Prop Payne Haas, battling a finger complaint, also needed attention from medical staff.
England international Farnworth left Tuesday's training session early to have his left quad strapped.
The Broncos told AAP none of the four were in doubt for Sunday's NRL grand final against Penrith, and all were named in an unchanged lineup when the team lists were released on Tuesday afternoon.
Forward Kobe Hetherington said he had spoken to Farnworth following the session.
"I just spoke to him before. He said, 'I'll be right'," Hetherington said.
"He's a tough bugger. He'll be right to go."
Walsh was on the ground for eight minutes receiving assistance from Broncos' medical staff with what appeared to be a hamstring or glute issue.
The last thing Brisbane need is for the 21-year-old whiz kid to be at anything other than his best against the Panthers.
Walsh was kicking his left leg out in the minutes after receiving treatment, but joined the main group and appeared to be moving freely.
"He was still running around," centre Kotoni Staggs said of Walsh.
Reynolds was on the ground for a minute and got up manipulating what appeared to be a knee or quad complaint, before also rejoining training.
"I'm all good. Just a bump," the 33-year-old said at the end of the session.
Haas, who was wearing a 'no-contact' red bib, appeared to have an issue with a hand and went for medical attention during the session. He was still involved in tackling drills.
Farnworth's centre partner Staggs said the Dolphins-bound weapon was integral to the Broncos' plans in the decider after he scored two tries and starred in last weekend's 42-12 preliminary final win over the Warriors.
"Herbie showed everyone last week what he can do when he is fit and ready," Staggs said.
"He is probably one of the best centres in the game this year and deserves all the credit.
"He can do stuff I can't do, and I can do stuff he can't do. When he does something good I want to match what he does."
