Richmond football manager Greg Miller has resigned from the Tigers board so he could concentrate on on-field matters, according to a report.

Miller relinquished one of his two roles and was replaced on the board by former Tigers skipper Tony Free, the Nine Network's The Footy Show reported.

Miller, who will remain as the club's general manager of football operations, has been criticised in the past for having the dual roles, especially with the Tigers performing poorly on the field in recent seasons.

Free will be the board member who oversees the club's football department, according to the report.

A statement from Richmond president Gary March was read out on The Footy Show.

"The board has been searching for some time for a contemporary player who will help the club build its young list," it read.

"Greg has retired from the board and will be able to concentrate on his role as general manager of football operations.

"As (we) continue to expand and grow the football department his experience will be vital."

Miller was the only board member in the AFL who also had another paid role at the club.

Miller is also a minor shareholder at North Melbourne, where he was previously the club's chief executive.
