Celtic will face Malmo or Vidi for a place in the Champions League group stages should they win their qualifier against AEK Athens.
The Scottish champions will reach the play-off round if they see off Greek side AEK in a tie beginning with Wednesday's first leg at Celtic Park.
They would then play either Malmo — in a repeat of a tie won by the Swedes in 2015 — or Hungarian side Vidi, with the prize being a place in the group stage for a third time in four seasons.
Celtic, who started the defence of their domestic title by beating Livingston 3-1 on Saturday, began their Champions League journey on July 10 — five days before the World Cup final.
A 3-0 away victory against Armenian champions Alashkert was followed by a win by the same scoreline in Glasgow eight days later.
Two goals from Odsonne Edouard then helped Celtic beat Norwegian giants Rosenborg 3-1 on home soil, before grinding out a 0-0 draw in the away leg.
Malmo have beaten Kosovo's FC Drita and Romanian outfit Cluj so far, while Vidi saw off Luxembourg's F91 Dudelange and Bulgaria's Ludogorets Razgrad.
