Broncos training scare as star trio get leg treatment

Brisbane received a scare at Tuesday's training session, with star fullback Reece Walsh, captain Adam Reynolds and centre Herbie Farnworth receiving treatment on their left legs.

Prop Payne Haas was also battling a finger complaint.

Farnworth left the training session towards the end and had his left quad strapped by staff.

The England international did not return to training.

The Broncos told AAP all four stars were not in doubt for Sunday's NRL grand final against Penrith.

Forward Kobe Hetherington said he had spoken to Farnworth.

"I just spoke to him before. He said, 'I'll be right', in his accent," 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 physiotherapist Luke Anning on what appeared to be a hamstring or glute issue.

The last thing Brisbane need is for the 21-year-old whiz kid at anything but top gear against the Panthers.

Walsh was kicking his left leg out in the minutes after receiving treatment, but joined the main group and was moving freely.

"He was still running around," Broncos centre Kotoni Staggs said of Walsh.

Reynolds was on the ground for a minute and got up touching what appeared to be a knee or quad complaint, before also rejoining training.

At the end of the session the 33-year-old wandered over towards the media.

"I'm all good. Just a bump," he quipped.

Haas also appeared to have an issue with a hand, and went to see Anning during the session.

AAP was told that as of Monday night none of the Broncos players in the top 22 had any injury concerns.

Haas also had a no-contact red bib on, but 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 the 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."
