The Pittsburgh Steelers will honor late owner and chairman Dan Rooney, who died in April, by wearing a special patch on their jerseys this season.
The circular patch is emblazoned with the letters DMR - which stands for Daniel Milton Rooney - inside a shamrock shape that pays tribute to Rooney's beloved Ireland.
Rooney served as the United States Ambassador to Ireland from July 2009 until his resignation in December 2012.
