SYDNEY will continue to be cautious with superstar forward Lance Franklin's troublesome heel but he's no chance of missing Saturday's clash with Brisbane at the Gabba.

Franklin was a shock inclusion to the team that beat Fremantle by 59 points at the SCG last week, despite being ruled out of the game by the Swans on Monday.

The four-time Coleman medallist had missed the previous three games with a bruised heel but returned with three goals from 19 possessions against the Dockers.

With a healthy lead against Fremantle, coach John Longmire was able to rest the 31-year-old for the latter stages of the win but said on Monday that the club would look to increase Franklin's minutes against the Lions. 

"That's our aim, but this is an unusual injury and it's really hard to predict," he said.

"The plan will be to keep him going and keep building up his game time.

"He played reduced minutes (against Fremantle) which was a bonus when you consider he was coming off no training, but he's pulled up really well so that's a really good sign.

"That’s the real positive to come out of the game."

Longmire acknowledged there could have been a temptation to give Franklin's injury an extra week to improve, but when he saw the West Australian striding around the SCG at last Thursday's closed training session, those thoughts quickly disappeared. 

"When he trained flat out and moved as well as he did on Thursday, and did everything he had to do, you'd need a pretty strong argument to not play him," he said.

"You wouldn't do it for every player either, and everyone is different.

"But he's shown a capacity to perform off very little training and not everyone is able to do that, so that came into the equation as well."

The Swans received further good news with midfielder Zak Jones cleared of any concussion issues after a head clash against the Dockers left him dazed in the final term.

Jones came from the ground shortly after and played no further part in the game, but Longmire said that was purely a precaution and the 23-year-old hasn't had any symptoms since.
