Yovicsin was born in Steelton, Pennsylvania and graduated from Gettysburg College in 1940. He returned to Gettysburg as assistant football coach in 1948 and was the head coach there from 1952 to 1956, tallying a mark of 32–11. During his 14 years at Harvard, Yovicsin amassed a record of 78–42–5. He helmed the Crimson during the famous 1968 Harvard–Yale Game, in which Harvard mounted a late comeback to tie Yale, 29–29. Yovicsin's role as coach is mentioned many times in the documentary Harvard Beats Yale 29-29, where players on both the Harvard and Yale squads talk about his professorial bearing.
