Brisbane assistant coach Ivan Henjak says Darren Lockyer's shock NRL comeback against Parramatta on Friday night is not Origin driven.

A successful return will clear the decks for Queensland selectors to pick the champion five-eighth for the must-win return clash with NSW at Suncorp Stadium on June 11.

After a few previous failed comebacks, concerns are Lockyer is motivated by wanting to help Queensland level the Origin series.

But Henjak said Lockyer was finally pain free after further surgery on his right knee and would not take such a massive risk.

"The one thing I know about Lockyer is when he makes decisions he thinks them through carefully," said Henjak after Lockyer trained strongly.

"I don't think he'd be putting himself at risk if he honestly didn't feel that the knee was right and it wouldn't jeopardise his whole season.

"Sure he wants to play Origin, I've got no doubts about that but I don't think he'd jeopardise his whole season for that."

All eyes were on Lockyer at Thursday morning's session and he moved quite freely, stepping and jinking and kicking.

"We'll just see how he licks the bin out overnight and if he pulls up well in the morning, we'll be right," said Henjak using a racing analogy.

Lock Tonie Carroll got out of his sick bed to train but the `flu kept winger Darius Boyd away from his teammates.

"Darren had a bit of a run yesterday and pulled up pretty good and we've left it in his corner," said Henjak.

"He trained pretty good and looked pretty sharp.

"He hasn't felt the pain that he's had before and he's been able to move a lot more freely so there's definitely light at the end of the tunnel for him."

Lockyer's training session ended in amusement and embarrassment when he "bombed" a certain try which fortunately didn't cost the Broncos a win.

Lockyer was given the honour of ending the final training session of the week at Red Hill by scoring an unopposed try.

It's a Wayne Bennett ritual, one players have a bit of fun with.

But for Lockyer it ended in laughter after he sidestepped the imaginary defence and dived over under the posts for his "try".

Unfortunately he lost control of the football with an amused Corey Parker drawing a square with his fingers in the air indicating the decision be referred to the video referee.

Lockyer brushed himself off and with a smirk walked over to Bennett for a lengthy discussion about his eagerly awaited comeback game.
