Corey Parker was yet again impressive in the Broncos' narrow loss to the Roosters.

Broncos teammates insist there is no question Corey Parker will take his place in Saturday's Qualifying Final against the Cowboys at Suncorp Stadium despite the inspirational lock forward failing to complete Wednesday morning's training session.

The second-last field session before a spot in the Preliminary Final goes on the line, Parker left the field early with a hamstring strain and was straight inside to begin treatment.

It would be a monumental blow to the Broncos if they were forced to do without his work-rate, offloads and goal-kicking with so much at stake but Sam Thaiday dismissed suggestions it would keep Parker from playing this week.

"I'm sure he'll be fine. It takes a lot more than that to keep Corey Parker off the football field," Thaiday said of his 33-year-old teammate.

"If you know Corey and you've ever played football with him it takes a lot to stop him from going out onto that field.

"It's been a long year for him and he's played a lot of football so just being smart, that's all we're doing.

"He'll want to be there for sure. If need be we can cover for him but we're not stressing too much."

 

Having finished Tuesday's session early due to a foot strain he picked up against the Rabbitohs in Round 25, Alex Glenn completed the entire session on Wednesday and was similarly confident that Parker would recover in time.

"Cozza's good. He's icing up at the moment. Similar thing to me, it's just precautionary," Glenn said after the session had completed.

"His hamstring, it felt a little bit funny yesterday so he knows his body well and what he has to do so he knocked it on the head towards the end of the session and he's gone in and got some treatment.

"He'll be great for team run on Friday."

Glenn was suspended for the game against the Storm in Round 26 but with the foot injury was able to enter a 'no contest' plea to the charge that eliminated the potential for any carry-over points heading into the finals series.

"I didn't want to miss any games but it worked well for me in my favour," Glenn said of his one-game suspension.

"I've got no carry-over points going into the finals which is something you want to have and my foot's healed up perfectly.

"All last week I was off my feet and just trying to make sure it was recovering as best as it could without doing any heavy running or anything.

"I got rested yesterday; it was my first run back so just precautionary. We didn't want to overdo it in the first session but ran great out there today, feel really confident and got through the whole 'sesh' which was good."
