After graduating from Ohio State's dental school in 1945, Horvath signed to play for the
Cleveland Rams of the
National Football League. Horvath, however, applied for a commission to join the
U.S. Navy and was sworn in as a
lieutenant j.g. that August. He was sent at first to
Naval Station Great Lakes in
Illinois for training, where he practiced dentistry and acted as an assistant to Brown, who had entered the Navy and was coaching the base's football team. Before his discharge from the Navy in 1947, there was speculation that Horvath might join the
Cleveland Browns, a new team coached by Brown in the
All-America Football Conference (AAFC). Led by quarterback
Bob Waterfield, Los Angeles finished the season with a 6–6 record in 1947. Horvath rushed for 68 yards and had three receptions. Horvath, who worked as a dentist in the offseason in Los Angeles, was released by the Rams in 1949. He signed with the Browns a week later, closing his dental office and moving to Cleveland to reunite with Brown. Cleveland finished the season with a 9–1–2 record and won a fourth straight AAFC championship. The AAFC disbanded after the season and the Browns were absorbed by the NFL, but Horvath decided to quit football to practice dentistry back in California. ==Later life and death==
