3-2-1... and we're back in the room.

Our marathon Scottish Cup third round coverage continues with holders Celtic in action at home to Falkirk.

We need a wee rest after all that action since before the mid-day kick-off in Dumbarton.

So there will be a little hiatus until we return about 19:00 for the build-up to tonight's remaining Saturday cup tie as holders Celtic host League 1 leaders Falkirk.

Partick Thistle manager Ian McCall claims striker Brian Graham was punched by one of the Dundee United players.

"I've not seen it, but Kenny Arthur seen it, my goalkeeper coach has seen it," he tells BBC Scotland. "The boy, I don't know his name, just punched Brian Graham. We're winning 1-0, that's an automatic red card, its crazy, it's nuts.

"There's no place for that in football, it's just bizarre, it was like an amateur game."

McCall was also unhappy with the winning goal, feeling Mouhamed Niang was fouled by Nicky Clark in the build up.

"For the winning goal, it's a stonewall foul - Nicky Clark has just pushed our guy on to the goalkeeper," adds. "It should never have stood.

"We just feel really hard done-by,. If the referee and the linesmen do their jobs properly, the outcome could have been different."

Hamilton head coach Brian Rice: "We dominated after the first 20 minutes. It's not a 3-0 game - not by a hundred miles.

"We created really good chances and missed a brilliant one at 1-0 down with Moyo's header.

"We lose another penalty and don't get many breaks."

Dundee United manager Micky Mellon explains his yellow card after arguing with one of the assistant referees during the 2-1 cup win over Partick Thistle.

"I enjoy the banter with the referees who want to have the banter and he was giving it back and if he says he wasn't then he's telling lies," he tells BBC Scotland.

"I was having banter with him, but then he decided he wants to call over his mate and exert a bit of power and the referee who hadn't heard anything decided he was going to back his mate."

St Mirren manager Jim Goodwin: "We suffered real disappointment here a couple of weeks ago and it would have been easy to let our season fizzle out.

"We started really well and were in control. The goal was a real bit of class from Jamie McGrath, who has shown that most of the season.

"It was similar to our last game here. We deservedly went in front but weren't ruthless enough."

Aberdeen, Dundee United and Livingston didn't get it all their own way, but in the end, they join four other top-flight sides - Kilmarnock, Motherwell, St Johnstone and St Mirren - in progressing to the last 16.

Inverness Caledonian Thistle, who beat Premiership side Ross County in Dingwall last night, have now been joined by fellow Championship team Morton.

There's three through from League 1, with Clyde, who securing the only mini-shock of the day with a win away to Championship side Ayr, being joined by Forfar and Montrose.

Stranraer are the only survivors from the fourth tier.

Formartine United manager Paul Lawson, the former Motherwell midfielder, tells BBC Scotland: “It was a tough afternoon, we knew it was going to be.

"If we had taken our early chance, it would’ve given the boys confidence. We looked nervous early on, but we were holding our own without playing great stuff.

"But we can’t look too much into this result. We won’t come against sides like this every week."

Motherwell enjoyed the biggest win of the day, 5-0 away to Highland League side Formartine.

Manager Graham Alexander tells BBC Scotland: "Credit to the boys, the were very good mentally and physically.

"The warning signs were there. We got a bit of fortune with the first goal, but we asked them questions and made them defend.

"It was great to see all the front three scoring. We had to earn the right to play and win today. I think we did that very well.
