Burnley 0-0 Lincoln
I didn't think the challenge was too bad, but I may have been wrong. Anyway, we have just over half an hour to go and still no goals. The National League leaders are 66% of the way to another fine result.

Barton has definitely led with his arm there.
Very, very lucky, Joey.
Burnley 0-0 Lincoln
Joey Barton flattens Alan Power in midfield in a strong but reasonably fair-looking challenge, but Lincoln boss Danny Cowley is livid, squaring up to one of the Burnley coaches in the technical area.
Burnley 0-0 Lincoln
Both sides have now wasted one golden chance each, though that Andre Gray miss probably would win a round of top trumps.
This game feels like it has largely been free-kicks. I make that free-kick number 22.
Burnley 0-0 Lincoln
Almost a mistake at the back for Burnley now as right-back Tendayi Darikwa is unsure whether to head or chest a ball away and ends up selling Tom Heaton short, but the England keeper is alert to it and dives on it.
And then a great chance for Burnley! Andre Gray is onside to meet a free-kick, his technique deserts him though and he ends up toeing the ball well wide!
Burnley 0-0 Lincoln
Paul Farman is able to continue. Burnley had started the second half at 100mph so that lengthy delay has not been helpful to their hopes of building momentum.

That was a bit old school.
A few referees would have been reaching for a card there.
Burnley 0-0 Lincoln
Burnley release Scott Arfield into the area, keeper Paul Farman is out quickly to reach the ball and a collision is inevitable. Arfield catches the keeper heavily and he'll need some treatment.
Burnley 0-0 Lincoln
Away we go!

Here they come. Have they brought goals with them?

Millwall v Leicester City (15:00 GMT)
Football Focus
Millwall manager Neil Harris tells Football Focus: "Leicester are the Premier League champions and have a very talented squad. We like the thought of being the underdog.
"At The Den we are going to make it competitive but whatever 11 they put out they will cause us problems.
"We've played two really good Premier League teams in Bournemouth and Watford and deservedly beat both of them. We have to be at the top of our game and hopefully catch Leicester cold at times.
"The atmosphere will be electric, it's a great place to play when it's full and the Leicester fans get behind their team as well so it will be a great atmosphere."
Burnley 0-0 Lincoln
If Burnley do need to make a change from the bench they aren't blessed with a massive amount of options.
They do have Ashley Barnes available, while 19-year-old striker Dan Agyei is the other option, fresh from a loan spell at Coventry.
Burnley 0-0 Lincoln
If you missed that first half, you didn't miss much. This was about the pick.

There is surprise in the scoreline because of the distance between the two teams but in the quality of the play there is no surprise.
The teams are evenly matched and I have been really impressed with Lincoln.
Burnley are playing how Burnley play. They are playing a team very similar and they are matching them. Burnley have to hope that their quality shows through in the end.
No goals yet but the suspicion that an upset is very much in the air. Here's a reminder of what is still to come.

Burnley have been sub-par in this half but they end with a great chance to take the lead. A long free-kick is pumped forwards, centre-half James Tarkowski juggles with the ball neatly on the edge of the area and tees up Scott Arfield - but the Canadian smashes it well over the top. You expect an international to at least get that on target.
Burnley 0-0 Lincoln
At a push that might count as a shot on target as Lincoln defender Sean Raggett floats a header at Tom Heaton. It was never going to go in though.
There will be a replay if required. And it may well be.

I think Lincoln manager Danny Cowley will be satisfied and proud of his players.
You know they are going to work hard but their belief has been impressive.
They want to get the ball down and the tackling in midfield has been impressive.
