St Mirren are enjoying a generally excellent season, so will this be the start of a memorable cup run?
Right now, Stephen Robinson’s side are seventh in the Premiership, despite being on the wrong end of a 4-0 drubbing at Celtic Park on Wednesday.
Nevertheless, at home, the Buddies are unbeaten in ten matches, most-recently holding Hearts to a draw a fortnight ago.
In Scottish Cup terms, the Saints won this competition in 1926, 1959 and 1987, beaten by St Johnstone in the semi-finals two years ago.
St Mirren have only fallen at the cup’s first hurdle thrice since 2007, so will be confident of victory here.
Dundee meantime were relegated from the Premiership last year, with an immediate return looking like a tough task.
The Dark Blues are third in the Championship, five points below surprise leaders Queen’s Park.
Due to Dens Park’s now infamously terrible pitch, Gary Bowyer’s side haven’t played a home game since 2 January, so will be thankful to have been drawn away in this tie.
The Dee’s one and only Scottish Cup success came in 1910, more recently featuring in the 2003 final.
They needed extra time to see off Airdrieonians in round three, eventually prevailing 6-2, but St Mirren are big favourites to advance through this one.
