Newport 1-1 Brighton
Ooh! Unlucky from Lewis Dunk.
He finds himself in space, about 25 yards from goal, and with nobody closing him down he has a strike at goal and it grazes the side netting. Good effort.

Kevin Ellison, who came on for Newport in added time, is 42 next month by the way.
He was released by Morecambe in the summer and was looking at jobs in factories and in special-needs education before Michael Flynn asked him if he wanted to play on.
Wouldn't it just be the FA Cup for him to score the winner?

Can Brighton recapture that tempo to their play?
Newport 1-1 Brighton
WHAT A SAVE!
That is brilliant from Tom King. A Bernardo cross from the left is met by Lewis Dunk, and King, flying to his left, does superbly to tip it away at full stretch.
Newport 1-1 Brighton
Brighton have started the better in extra time.
I have no idea what formation Newport are playing anymore. They made changes chasing the game so are now, as a consequence, a bit unbalanced.
Newport 1-1 Brighton
We're under way in exra time.
Newport 1-1 Brighton
Who are people backing now?
Newport haven't played since Boxing Day remember - is that a positive or negative at this stage?
Brighton just don't know how to win. They've drawn eight Premier League games this season.
Newport 1-1 Brighton
It was a double change by Newport at the end by the way - Kevin Ellison and Jamie Proctor are both on to replace Matthew Dolan and Lewis Collins.

Don't you just love the FA Cup!
Just when you thought this was all done.
Newport 1-1 Brighton
Into extra-time we go.
I would love to say cup magic but I mean...
Adam Webster own goal (90+6 mins)
Where has that come from!?!
Wow, wow, wow! That is an absolute shocker from Jason Steele!
He flaps at a cross from the right, and it just hits Adam Webster and ricochets into the net.
Newport 0-1 Brighton
We're into the sixth minute of added time...
Solly March is replaced by Bernardo for Brighton, while veteran Kevin Ellison is on for Newport.
Newport 0-1 Brighton
Newport look absolutely exhausted right now - not having played since Boxing Day looks like it has caught up with them in the dying stages of this game.

Absolutely gutted for the Newport lads, they've got a moment to get back into this now but I can't see it.
It was a fantastic tempo to that attack, I expected to see more of that from Brighton and Newport have done so well to limit them until now.
Newport 0-1 Brighton
We're into added time now. I have no idea how many minutes were signalled but I do know that Newport have it all to do now.
Solly March (90 mins)
WE'VE GOT A WINNER!
That is superb from Solly March. He finds space on the D on the edge of the area and curls it around the defender, past the keeper, into the bottom corner.
Graham Potter is delighted on the touchline.
Newport 0-0 Brighton
Good goalkeeping from Jason Steele.
Newport hurl a long throw in into the area but Steele just knocks everyone out of the way and claims it.
Newport 0-0 Brighton
Two minutes to go. Extra-time is looming...
Newport 0-0 Brighton
It's all very intricate from Brighton as they try and to work an opening but are crowded out.
They come again though and Percy Tau does well to create some space but Tom King is behind it at his near post.
Five minutes of normal time left...
