Ulsan Hyundai FC 2–3 Gangwon FC

Kim Young-Gwon gave Ulsan Hyundai FC the lead in the 15th minute, then handed it straight back to Gangwon FC with an own goal in the 43rd, the kind of afternoon K League 1 nightmares are built on. J. Sekidika had already levelled for Gangwon in the 35th before Young-Gwon's self-inflicted blow made it 2-1 to the visitors, and Jung Seung-Hyun's 55th-minute equaliser only briefly restored parity. Kim Dong-Hyun settled it in the 82nd, completing a 3-2 comeback win for a Gangwon side that had managed just one victory in their previous five outings. Ulsan, second in the table on 37 points and the stronger side on recent form, now also carry the record of losing their only head-to-head with Gangwon this season. Watch Kim Dong-Hyun's 82nd-minute winner, but don't skip past the moment Young-Gwon undoes his own opener.
