Goal-line technology will be used at this season's Champions League final in Milan and Europa League final in Basel, UEFA said on Friday.
Greek Theodore Theodoridis will take over as acting general secretary of European soccer's governing body, it said, to replace Gianni Infantino who was elected as FIFA president last Friday.
Goal-line technology, used to decide whether the ball has completely crossed the line, was approved by the International Football Association Board (IFAB) in 2012.
It has been since been used in major European domestic leagues and at the 2014 World Cup.
Theodoridis was previously UEFA's deputy general secretary.
The organisation is looking for a new president after Frenchman Michel Platini was banned from soccer for six years over ethics violations.
