Since suffering a fracture in his foot in Round 4, Lynch has not appeared for the Tigers as he underwent rehabilitation.
The Tigers had been holding out hope Lynch could make an AFL return this year to help aid Richmond's finals push, however, upon recent consultation with Richmond's medical team, it was determined the 2022 Jack Dyer Medal winner would not return to the field this season.
Richmond football boss Tim Livingstone stated a cautious approach to Lynch's long-term health was paramount.
"Tom is such a significant player for us, so it is important that we get this right," he said.
"We have monitored the bone throughout the season, and the healing process has been slow - but we have not wavered from the beginning that the priority would be Tom's long-term health.
Tom Lynch has been ruled out for the remainder of the 2023 season due to the foot injury that has kept him sidelined since Round 4.
We look forward to seeing you back, Lynchy 💛

"It is frustrating because we would love to have Tom playing for us, but even more, we want him fit and firing for the long term. This course of action has been recommended by our medical staff and will give Tom the time required to get this right for the future."
With Lynch remaining sidelined, the Tigers travel to Western Australia to face the Eagles at Optus Stadium on Sunday evening.
