Ryan Rydel becomes the first Stockport player to be shown a yellow card for a challenge on Jake Forster-Caskey.

A shove from Jake Forster-Caskey gives Stockport another free-kick from not far outside the penalty area.

Macauley Southam-Hales' shot again is comfortably taken by Craig MacGillivray.

Anthony Hayes must not be happy with what he's seeing and he makes a double change with just under 30 minutes of the half to go.

Albie Morgan and Charlie Kirk go off with Jesurun Rak-Sakyi and Diallang Jaiyesimi coming on.

Tyreece Campbell - who is already on a yellow card - gives away another free-kick for a challenge on Akil Wright.

Ryan Rydel's free-kick goes straight into the hands of Craig MacGillivray however.

Charlton having their best spell in possession so far this half but again aren't really threatening with much going forward.

They've had just the one shot on target to Stockport's four so far.

It definitely feels like this match is starting to bubble over as tempers are still high between players on both sides after that challenge a few minutes ago.

For the second time the referee has to give them all a talking to.

Macauley Southam-Hales is back up on his feet but was being seen to by the medical staff for a good few minutes there.

No cards were shown anyway, which doesn't seem to have gone down well with the home crowd.

Not a pretty sight as Stockport defender Macauley Southam-Hales goes down and falls into the advertising hoardings in a challenge with Ryan Dobson.

Players from both teams gather in a bit of a scuffle, as the referee tries to calm emotions down.

Ooof Stockport almost have a second but Ryan Rydel's strike hits the post for the second time in the game.

His free-kick curls perfectly up and over the Charlton wall and has Craig MacGillivray beaten in goal, except the ball clips the woodwork and goes wide.

Tyreece Campbell is the first player into the referee's book as the Charlton teenager is late with his tackle on Will Collar.

Another warning shot from Stockport as Will Collar wins a free header in the box from a free-kick.

He doesn't get the ball on target but Stockport are certainly starting this half the way they finished the previous one.

Charlton have made a change during half time with George Dobson coming on in place of Chuks Aneke.

We're back up and running at Edgeley Park.

Are we going to get a winner in this next 45 minutes or are we going to extra time?

In case tonight's FA Cup replay action isn't enough for you, we've got another helping tomorrow evening as well.

This time, League Two Gillingham host National League side Dagenham & Redbridge, after their first match ended in a 1-1 draw.

Kick off is at 19:15 GMT and you'll be able to watch it on BBC Three and iPlayer.

We'll also have live text coverage on the BBC Sport website.

And we do indeed go in all square at the break.

An own goal from Akil Wright put Charlton in front after seven minutes before Will Collar equalised shortly before the half hour mark.

We've had two minutes of added time tagged on to the end of this half.

Charlton are probably quite happy to go in with a draw - if they do - on the balance of things so far.

Got to be said but Charlton are looking very nervous whenever the ball goes into their box or even when they send it back towards Craig MacGillivray in goal.

Will Collar goes down over an outstretched foot from Albie Morgan and again Stockport have the chance to fire the ball into the box from just inside the Charlton half - almost identical to where they scored from.

It gets nodded back across the box to Myles Hippolyte and there are cries of handball as his shot bounces back off a Charlton player, but the referee isn't having it.

Charlton have had all the possession for the last couple of minutes but don't seem to quite know what to do with it when they're going forward, to the point that they end up going all the way backwards to start again.

Stockport are enjoying a decent spell here, forcing Craig MacGillivray into repeated saves.

The first from Will Collar and the second from Paddy Madden in two minutes has the Charlton keeper put to work.
