Article 31, point 14 directly regulates how clubs can replace goalkeepers in the event of a serious injury. It was precisely this provision that FC Barcelona used when they brought in Wojciech Szczęsny and put him in the squad to replace Marc-Andre ter Stegen.

"If a club is unable to count on the services of at least two goalkeepers registered on List A due to long-term injury or illness, it may temporarily replace the goalkeeper in question and register a new one at any time during the season. An injury or illness is considered long-term if it lasts at least 30 days from the day on which the injury or illness occurred. If the goalkeeper recovers before the end of that match of the 30-day period, the player must, however, remain off List A until the end of that period," reads the regulations on the UEFA website.

Now, however, another question arises. Ter Stegen suffered a torn patella tendon injury in September, which was initially supposed to rule him out of action until the end of the season. However, it turns out that his recovery is going very well and the German goalkeeper has already returned to individual training on the pitch. Spanish journalists indicate that the goalkeeper's goal is to return to full fitness by the end of April and play at least one match this season. The Champions League final is scheduled for May 31, and "Sport" wonders whether ter Stegen can play in this edition of the competition.

On paper, it is possible. However, the injured party in such a situation will be Wojciech Szczęsny. "When an injured or sick goalkeeper is able to play, he may return to his substitute position. The return of the first goalkeeper must be announced to the UEFA administration 24 hours before the next match in which the original goalkeeper is available to play" - this is the rest of Rule 31.14.
