Luton 1-0 Harrogate
Around 28 minutes on the clock at Kenilworth Road where the home side still lead.
Luton boss Nathan Jones has spoken highly about his returning assistant and Hatters legend Mick Harford.
He is back in the dugout after treatment for cancer and he received a warm welcome before kick-off.
Jones told BBC Radio 5 Live: "He usually puts others before himself. He had to put himself first and he left a big hole.
"It was like he was never gone [when he returned]. We're really proud of him, he has done so much for this club.
"As a player he was a legend, as a manager he had some good and bad times. It shows how valuable he is to us, we are proud to have him.
"He shows strength and humility every day. That was long winded but it's difficult to say a few words about him."
This is the place to be for goal clips from today's ties.
We'll bring you all the tap-ins, long-range stunners, own goals and penalties right here.
The only ties we cannot provide this service for is the 14:00 GMT tie between West Ham and Leeds and the 17:10 match between Nottingham Forest and Arsenal as they are both ITV games.

Harrogate fans will have had to set their alarm clocks very early to get to this tie. Those that have made the effort are making themselves heard.
The League Two club have won a number of early corners while Luton's Reece Burke has received treatment for an early knock.

Mark P Makey: As a Leeds supporter I see similarities at what is happening at Newcastle. If they go down it will be a disaster for the club and life in the Championship will be very tough. Eddie Howe may not survive.
JFT97: Perhaps Steve Bruce was doing a fine job.
Steve Thompson: How does Eddie Howe escape criticism? Surely he was only bought in for the short term?
There's been plenty of reaction to Newcastle's defeat to League One Cambridge. Is the honeymoon period over for Eddie Howe?
Luton 0-0 Harrogate
Image source, Getty ImagesNo goals yet in the early kick-off but Luton Town assistant boss Mick Harford has been talking about his return to the dugout after cancer treatment.
"I still have to carry on with my appointments at the hospital, but it's great to come back into such a positive, bubbly environment," he says.
"It makes me feel a lot better, and I feel really positive about moving forward.
"It takes your mind off things and you can get stuck into your work here. I can just be focused on the football.
"The support I've had from supporters, the club, the board, the management, staff and players has been unbelievable, and really helped me through. I can't thank them enough."
Premier League clubs to fall at the first hurdle:

Luton Town manager Nathan Jones is happy his side is facing a League Two side rather than a fellow Championship club.
He tells BBC Radio 5 Live: "Anything but a Championship club, not that we're scared of them but you prepare for the Championship matches through the season. When you get to the cup you want something a bit different."
Ready for a bit of live action? Lots of noise at Kenilworth Road as players from Luton and Harrogate emerge from the tunnel. It's Championship v League Two.
From Kidderminster to Boreham Wood, Saturday was a day of celebration for lower league teams in the FA Cup. Cambridge United's players really enjoyed themselves on the Newcastle pitch at full-time.

He missed last weekend's game at Chelsea after testing positive for Covid-19 but is back to take charge of the tie against Shrewsbury.
In his programme notes for today's game - written a few days ago - Klopp says: "This is one of the strangest programme columns I have ever written, because I have no idea if I will be in the stadium with you, leading my team in person – or watching from home.
"What I can say is that I’m doing OK and looking forward to getting back to work."

Staff at Luton raised more than £27,000 to help towards the cost of his cancer treatment and he has now been given the all-clear to resume his day-to-day role.
