While still being signed to the Demons until the end of 2024, Tomlinson will step into the open market in hope of gaining interest and more opportunities at AFL level.
The 29-year-old managed just the eight games in 2022, having fallen in the Demons' selection pecking order among their key defenders as he recovered from a season-ending ACL injury sustained last season.
"At the moment we're sort of in the hands of Timmy Lamb and the Dees, just to get something and another club to participate," Deledio said.
"For Tommo, he's a contracted player and loves the boys, loves the club, but he's frustrated he's not playing senior footy.
"You can understand that unfortunately his injury and (having) spent 12 months on the sideline, sometimes a knee reco can take a little while to get you back up to playing your best footy.
"He played some solid footy this year, was one of the best in the VFL in the flag they won, but Thommo wants to be playing senior footy at the age that he is.
"If someone comes we'll entertain and have a look at it and see whether it works best for both parties. But essentially he's contracted and happy to stay there if nothing comes about."
When asked whether clubs have made contact in regards to Tomlinson's services, Deledio stated things have been quiet, but the market could change.
"There's a few that are watching space in terms of what they can get done, where the cards fall," Deledio said.
"Things can change really quickly, as it did for Tommo, playing lockdown as a fullback, starting top 22 to struggling to find his way back in."
Tomlinson has played 168 games in the top flight, including 28 matches in three seasons with the Demons.
