Matthew Henry "Matt" McClung, Jr. (December 1, 1868 – March 3, 1908), sometimes referred to as Dibby McClung, was an American college football player, coach, and official. Born into a powerful southern family, McClung was raised in Memphis, Tennessee until he was accepted into Lehigh University. Immediately establishing himself as a skilled sportsman, McClung participated on both the school's football and baseball teams. He served as captain of the former in 1892 and is credited with turning it into one of the school's best ever football squads. McClung graduated from Lehigh in 1893 with degrees in metallurgy and mining engineering.
After graduating, McClung took a position as the coach of the Naval Academy football team. He served for one season, leading the team to a 5-2 record against a mediocre schedule. Following the season, he began a career as a college football referee which would span twelve years.
While working at the Joliet Blast Furnaces, McClung developed a severe tooth infection, which eventually gave him blood poisoning. He succumbed to the latter condition on March 3, 1908, at the age of just 39. McClung's death came before those of his parents and all six of his siblings. He was replaced just days after his death by W.J. Moore, a chemist who had worked under him at the plant. Following his death, McClung was memorialized by several of his former teammates and officials. When "Big Bill" Edwards wrote and published his book Football Days, he included McClung in his tribute to deceased college football players. He wrote that: "Richard Harding Davis and were two Lehigh men whose position in the football world was most prominent. The esteem in which they are held by their Alma Mater is enduring". Edwards also praised McClung and Dashiell's refereeing, stating that "Officials come and go. These men have had their day, but no two ever contributed better work. The game of Football was safe in their hands". Paul Dashiell, when interviewed by Edwards' for Football Days, spoke about his relationship with McClung. He said that:
