Motherwell's showdown with Celtic faces a channel switch up should the game go all the way to extra-time and penalties to avoid a clash with Rangers and Dundee.
The holders are first-up on a bumper night on action as they travel to Fir Park in a bid to secure a semi-final spot and a trip to Hampden.
The Premier Sports Cup Final victory over Hibs under Ange Postecoglou acted as a catalyst for Celtic's title winning campaign, but Motherwell boss Steven Hammell will be hoping to derail any hopes of retaining the trophy by booking a spot at the national stadium for the Steelmen.
It's a game that could see both sides pushed to their limit with a traditional knock-out format in place during the quarter final stage, meaning ties will be decided by extra time and penalties if the scores are level after 90 minutes.
