The UEFA European U-21 Championship's match for third place burst into life late on after Filipenko's late volley set up a fraught finish. The Czech Republic had enjoyed most of the play, but Lukas Vacha's 75th-minute dismissal for a second yellow card gave Belarus licence to show more ambition.
With just two minutes left on the clock, Oleg Veretilo's right wing cross found Filipenko who had peeled away from his marker. The centre-back's volley was firmly stuck and placed accurately, and gave Belarus a ticket to the Olympic Games for the first time.
Belarus join the competition finalists Spain and Switzerland together with the hosts as European representatives at the tournament which will take place in various venues across Great Britain next year.
