"I want to be involved with the team and the organization in any way I can," Rooney, 80, said Sunday before the Steelers' game against the Dallas Cowboys in Arlington, Texas. "I would want to become involved again in league matters where I can be helpful."
Rooney, a member of the Pro Football Hall of Fame, resigned from the ambassadorship Friday after serving one term since 2009, a typical procedure in U.S. State Department posts involving non-career employees, the Pittsburgh Tribune-Review reported Monday.
The Steelers listed him as "chairman emeritus" in his absence, the Pittsburgh Post-Gazette said.
His son Art Rooney is the Steelers' president.
