There was a problem with the balls in Scottish Cup sixth round draw and the process had to be restarted during the live Sky Sports broadcast yesterday.

One of the balls drawn from the container was discovered to already be open, with the contents inside visible leaking from within.

The whole thing had to be abandoned and a presenter struggled to keep the coverage going before the draw was eventually done again.

Celtic avoided an away tie at Dundee United and will instead host Championship side Greenock Morton.
