Jakub Kowalski from Korona Kielce has joined the first-division club Stal Mielec on a temporary transfer, where he will finish the current season. The wing-back is nearly 20 years old and was formerly in Legia Warszawa's youth setup. The loan was arranged for him to gain experience at a higher level. This decision was made because he performed well for Korona's third-tier reserve team, with four goals and seven assists in 20 games, but was only training with the first team without getting other opportunities. Stal Mielec announced that the loan agreement is until June 30, 2026, and that the player will return to Korona Kielce after his loan.
