In the 10th week of the Süper Lig, Galatasaray defeated Konyaspor 4-0 away from home. Beyond the score of the match, the fact that the yellow-red team made a total of 6 substitutions became a subject of curiosity after the game.
Under normal circumstances, teams have the right to make 5 substitutions during a match. However, the injury sustained by Konyaspor goalkeeper Bahadır Han Güngördü and his inability to continue playing due to a blow to the head triggered a special application in the match.

HOW DID THE RULE WORK?
Within the scope of football rules, in mandatory substitutions made due to suspected head trauma or head injury, the opposing team can also be granted an additional substitution right. This procedure is among the practices that prioritize player health.
The substitution made by Konyaspor following Bahadır Han Güngördü's injury provided Galatasaray with an additional substitution opportunity. Thus, the yellow-red team was able to exceed the 5-substitution limit and make a total of 6 changes.

Galatasaray made 5 substitutions simultaneously in the 61st minute. Leroy Sané replaced Yunus Akgün, İlkay Gündoğan replaced Aleksey Batrakov, Lesley Ugochukwu replaced Victor Osimhen, Deniz Gül replaced Lucas Torreira, and Renato Nhaga replaced Gabriel Sara.
The yellow-red team's 6th substitution came in the 69th minute. In this minute, Davinson Sanchez left the game and El Chadaille Bitshiabu entered the pitch.

For this reason, Galatasaray's 6 substitutions against Konyaspor were not due to an irregular situation, but rather resulted from the special substitution procedure applied after a suspected head injury.
