The disqualification was eventually shortened so that Kozakiewicz could compete at the 1977 European Indoor Championships in San Sebastián which he won in a new championships record of 5.51 metres. This started a very successful season in which he, among others, won the Summer Universiade in Sofia and set a new European record of 5.66 metres in the European Cup semifinal in Warsaw. In the entire year he suffered only one loss, at the 1977 World Cup, where, representing Europe, he came second behind the American Mike Tully.
