The Pittsburgh Post-Gazette reported Tuesday that the elder Rooney, who was inducted into the Hall of Fame in 2000 and now will be the team's chairman, has turned over its presidency to Art Rooney II.
His father, Art Rooney Sr., founded the team in 1933, and was inducted into the Hall of Fame in 1964.
"I just thought it was time," Dan Rooney told the paper. "Art has been involved with a lot of the business of the team. He was very much involved in the building of Heinz Field. I'll still do the community work and league work and things like that."
The Gazette report said there was no announcement to note the change in leadership, and it was discovered after media guides were distributed to news media on Monday.
Art Rooney II has been club's vice president and general counsel.
