On September 9, he scored his debut goal for Incheon United in an away match against his former club, Jeonbuk. He further demonstrated his offensive capabilities by scoring a heading goal against FC Seoul in a home match on October 16. In August 2012, Jung received a substantial salary offer for a transfer from Al-Sailiya Sports Club of Qatar, but he ultimately rejected the offer, choosing to remain with Incheon United. During his two seasons with Incheon United from 2011 to 2012, he played in 60 matches and scored 6 goals.
