Robert Dickey "Jack" Sisco (November 2, 1904 – December 18, 1983) was an American football player, coach, and official. He served as head football coach at the University of North Texas from 1929 to 1941. With a record of 74–37–10, Sisco is the second winningest coach in school history, behind Odus Mitchell. His teams won seven conference championships and tied for three others. A native of Waco, Texas, Sisco prepped at Waco High School playing under coach Paul Tyson. He went on to attend Baylor University, where he was a lineman on the 1924 Baylor Bears football team that won the Southwest Conference title. After his coaching career, he became a college football referee best remembered for a controversial call in the 1947 Red River Shootout between the Texas Longhorns and Oklahoma Sooners. To this day, some Sooner fans refer to this as the "Sisco Game". His great-granddaughter, Emilee Sisco, played volleyball at the University of Colorado.
