20:28: They are back underway at Patrick Thistle and the hosts have started the second half in brighter fashion.
Steven Anderson has just been booked and they are still struggling to keep possession.
But Aidan Fitzpatrick has fired an effort over the bar for their closest effort so far.
Hearts still destined for the semis.
20:21: Brendan Rodgers gave up the chance of a treble-treble when he left Celtic for Leicester.
But they remain favourites to lift the trophy after Neil Lennon guided them to a win over his former club Hibs in his first game since returning to the dugout.
To say he was pleased after watching James Forrest and Scott Brown strike for his side would be a bit of an understatement.
And he even found time for a little dig at the departing Rodgers after claiming it was the best Hoops performance he had see for some time.
“I am absolutely delighted, I got everything I wanted,” he said.
“I thought it was an outstanding performance from the team. We had total control, and I thought that was the best I’ve seen them play for a while.”
20:09: A reminder of the ball numbers for tonight’s draw. Note that Hearts are currently in control of ball four.
2 ABERDEEN OR RANGERS
4 PARTICK THISTLE OR HEARTS
20:00: The draw will start once the game at Firhill between Patrick Thistle and Hearts has finished.
A Christophe Berra header currently separates the two sides after a superbly executed set-play.
The defender just can’t get enough of the cup – both of his two strikes this season have come in this competition.
Frankly, the visitors dominated the first half and Partick can thank themselves lucky to be only one goal behind. The two teams have just gone in for half-time.
