DOM Tyson has declared himself a certain starter for Melbourne's clash with the Brisbane Lions on Sunday, despite the midfielder favouring his lower back at training on Wednesday morning.
Tyson started the session at Casey Fields with the main group but sought out the medical staff halfway through as they worked diligently to free his back up.
He then joined the rehab group working on the far side of the ground before jogging laps around the boundary.
Demon Brayshaw set for an extended rest
But Tyson, who had a career-high 32 disposals against the Western Bulldogs at the weekend, said there was nothing to worry about and he would be right to go against the Lions.
"It was just the fitness staff looking after me," Tyson said.
"Every now and then you have a lighter Tuesday or Wednesday and then we'll have another main session Friday and be ready to go Sunday."
Tyson also disappeared into the rooms to receive treatment during the session.
The midfielder was not the only sore Demon with forward Jack Watts also on light duties on Wednesday.
Watts had a focus on taking the ball cleanly on the lead before completing some light running.
Matt Jones (back) and Sam Frost were also part of the rehab group as they worked on their conditioning.
Angus Brayshaw was absent from training after copping successive head knocks in the VFL.
The young midfielder is around a month from a return and the Demons will give him an "extended period" away from the playing field to ensure he recovers appropriately.
"I sent him a message yesterday (Tuesday) and he's a bit groggy as you'd expect," Tyson said of Brayshaw.
"He's been pretty flat about things but the club's handling it really well. He'll be fine and we can't wait to have him back out there."
Defender Heritier Lumumba (concussion) was also not out on the track.
Dean Kent moved freely and looks ready to return after missing last week's clash against the Western Bulldogs with a back complaint.
Young midfielder Alex Neal-Bullen has been in stellar form at VFL level and is a chance to play his first game for the season against the Lions.
Neal-Bullen played 11 games in 2015 but has been forced to bide his time with the added strength of the Demons' midfield this season.
Melbourne was comprehensively beaten at the contest against the Dogs and Tyson said that was something the club would be looking to fix against the Lions on Sunday.
The club's midfielders completed extra work in their positional groups at training as they look to improve their stoppage setups ahead of Sunday's game against the Lions.
