While still at Davidson, Ukrop played with the U.S. national B Team. After graduating from Davidson in 1993 with a bachelor's degree in classical studies, Ukrop went to the World University Games with the U.S. U-23 national team. He scored two goals and added an assist in the U.S. victory over Italy. That summer he also joined the Richmond Kickers of the USISL. The USISL had begun as a small indoor league in the Southwest U.S., but gradually expanded outdoor as well. In 1993, the Kickers joined the league, making the playoffs as a wild card team. They defeated the Charleston Battery, then lost to the eventual USISL champion Greensboro Dynamo.
