PFC Ludogorets Razgrad were denied a second UEFA Champions League victory against F91 Dudelange by David Turpel's 81st-minute equaliser.
Having put four past Dudelange without reply in Bulgaria last week, Stoicho Stoev's side were on course for another win and clean sheet when Roman Bezjak struck six minutes after the restart. The hosts responded with time running out through Turpel, but it will have done little more than irk a Ludogorets team who will encounter FK Partizan in the third qualifying round for the second season in succession.
It was Luxembourger titleholders Dudelange who were the aggressors in a quiet first half, Stélvio heading wide a corner from Sofian Benzouien and Turpel having a shot saved by Vladislav Stoyanov.
Five minutes into the second period, Turpel set up Joël Pedro, whose profligacy was immediately punished by Bezjak's precise strike from inside the penalty box. Dudelange had the last word, though, Turpel scoring with a shot after being set up by Yassine Ben Ajiba.
