It was truly the worst possible debut. Not only did he play out of position, but he even wore someone else's uniform. The result was a team defeat and elimination—everything was at its worst. It was the moment he had dreamed of, yet he made his debut in a way he could never have imagined. Lee Jung-hyo, Suwon Samsung's head coach, made a choice that ruined this one-and-only player's debut stage.
Here is what happened. On the 15th, at Yangsan Comprehensive Sports Complex during the 2026–2027 Hana Bank Korea Cup Round of 64 (second round) match between semi-professional team Busan Transportation Corporation (K3 League) and professional K League 2 side Suwon, the game was tied 1-1. In the early stages of extra time, head coach Lee Jung-hyo substituted out Kim Sung-ju, who was visibly exhausted and struggling to continue playing, and brought on Lee Kyung-jun, born in 2006. For Lee Kyung-jun, this was finally his "professional debut" since joining Suwon in 2024.
The problem was that Kim Sung-ju was a field player, while Lee Kyung-jun is a goalkeeper. Moreover, the role assigned to Lee Kyung-jun was that of a forward. As a goalkeeper with no field uniform available, he ended up wearing Park Dae-won's jersey, number 33, which did not bear his own name or number. To change the number from 33 to 31, white tape was forcibly applied, leaving a messy trace. For Lee Kyung-jun, who had imagined making his debut confidently on the field wearing a uniform with his own name and number, this was an unimaginable moment.
Having played for the youth national team as a goalkeeper, he spent over 30 minutes in extra time wearing an unfamiliar uniform and playing an unfamiliar role. However, he failed to make any significant impact from the forward position. Expecting him to show presence in that role was itself an unusual situation. To make matters worse, Suwon conceded a decisive goal during extra time and lost 1-2, resulting in elimination. The outcome made Lee Kyung-jun's debut even more of a nightmare.

Behind Lee Kyung-jun's appearance as a field player was an incomprehensible decision by head coach Lee Jung-hyo. On that day, only six people sat on the Suwon bench: goalkeeper Lee Kyung-jun and five field players. Although tournament rules allow up to nine players on the bench, Suwon had only six. The entire squad traveling to Yangsan consisted of just 11 starters and six substitutes. This was not due to a shortage of players. Just four days earlier, during a K League 2 match, Suwon had all nine bench spots filled.
However, all five field players were substituted in during the match. As the game entered extra time, one additional substitution became possible. With Kim Sung-ju unable to continue playing, the only remaining substitute card was "goalkeeper Lee Kyung-jun." This was the unavoidable reason Lee Kyung-jun took the field. If head coach Lee Jung-hyo had properly prepared the substitution list according to tournament regulations, while Lee Kyung-jun's professional debut might have been delayed slightly, it is highly likely that this would not have become a painful experience for the player.
Ultimately, head coach Lee Jung-hyo's initial decision to limit the bench to six players snowballed into ruining the professional debut of one 2006-born player, turning it into a nightmare. Furthermore, even though tournament rules allow up to six substitutions in extra time, limiting the bench to only five field players can be criticized as a choice lacking respect for both the tournament and the opposing team. Immediately after the match, Suwon fans expressed strong anger and disappointment—not only because of the result (losing to a K3 League team and being eliminated), but also because head coach Lee Jung-hyo's preparation process for that day's game appeared closer to complacency or arrogance than the "best effort" fans always expect.
