Waves of Cambridge players going towards the Mansfield goal and Ryan Donaldson has a strike tipped over the bar.

Just when Luton look to have done enough Daniel Nardiello pops up to scramble the ball over the line in a melee and almost certainly send this tie to a replay.

What did I just say? Kwesi Appiah takes advantage of some confusion in the Mansfield defence to bury the equaliser and gets booked for his over-zealous celebrations.

Sorry Mansfield fans, I think I just put the kiss of death on you.

Kwesi Appiah is so close to the equaliser to break Mansfield hearts, but Sascha Studer pulls off a fine save to his left. That may be it.

Marc McNulty, recently back from injury, wraps up the victory for the Blades from close range.

Bury get lucky there. Ricky Miller's fine strike hits the post and falls gratefully into the clutches of Rob Lainton.

Aston Villa loanee Enda Stevens puts a dangerous cross into the Latics box and defender George Elokobi diverts the ball into his own goal. Doncaster going through?

Blades striker Marc McNulty battles to win the ball on the edge of the Plymouth area but, having done the hard work, pushes his shot wide.

Accrington clearly don't want a replay down in Somerset and Shay McCartan's downward header looks destined for the back of the net, but comes back off the foot of the upright. Could not have been much closer.

Paddy Kenny makes a wonderful stop to deny Theo Robinson what could well have been a Doncaster winner.

Luton Town fan JP:, external If Luton manage to win I wouldn't mind an easier match in the next round. Arsenal, perhaps.

BBC Sport's Seth Bennett:, external Hello, cup tie here, 1-1. It's been all Accrington since the break. Yeovil are on the ropes.

Chesterfield battling hard to retain their lead. The Spireites have won one second round tie in 34 years... Could this be number two?

Mansfield have been under tremendous pressure at the back in the second half, but they take the lead in quite fortuitous circumstances. Rob Taylor hits a hopeful free-kick into the area and it is headed into his own net by Tom Champion .

This could be a winning start for new full-time Stags player-manager Adam Murray.

Still no goals at Boundary Park. Both teams have made changes but we're heading back to the Keepmoat to do it all again as it stands.

Preston have the chance to make it game over at Deepdale from the penalty spot when Paul Gallagher is clipped in the box, but the forward smashes his penalty way over the crossbar. Could he be made to pay for that dreadful effort?
