So close to an equaliser for Colchester!

Alan Judge clips a cross to the far post, Sylvester Jasper heads it goalwards but Jamie Jones superbly plucks it out of the top corner with his fingertips.

It's all gone a bit sloppy. BBC Radio Manchester's Bill Rice says the pitch is starting to cut up a bit too as the rain comes down in Essex.

Colchester have regrouped well after falling behind but without creating a clear-cut chance to level.

At the other end, Will Keane arguably should have doubled Wigan's lead but keeper Jake Turner produces a fine low block.

Jordon Garrick's header separates the two sides at the break.

But Rochdale are certainly not out of this. All to play for in the second half.

Closing in on half-time at the Crown Oil Arena.

Rochdale go the long, long way round from a free-kick to get into the Plymouth box but when Jake Beesley does work a yard of space he can only shoot straight at Michael Cooper.

Lovely football from Plymouth. Jordon Garrick and Ryan Hardie combine beautifully to release Ryan Broom, but under pressure the winger sees his stabbed effort fly wide.

Another chance for Colchester. This time a pull-back from the right picks out Freddie Sears, but the experienced forward fires over from 12 yards.

Rochdale looking for a route back into this tie as Abraham Odoh cuts inside and tries a curler from 25 yards.

Unfortunately his effort hits a team-mate, enabling Plymouth to scramble it clear.

Promising from Colchester. Noah Chilvers controls a cross from Junior Tchamadeu but his shot on the turn flies over.

The best moment so far from the home side.

Moments later Ryan Hardie does put the ball in the net for Plymouth. Unfortunately for the Scot, the offside flag cuts short any celebrations.

Ryan Broom's deliveries are causing Rochdale problems.

The winger arrows in another centre towards Ryan Hardie but Dale keeper Jay Lynch gets there first to unconvincingly punch clear.

Early penalty appeal by Colchester is waved away after Sylvester Jasper took a tumble in the box.

Moments later the man on loan from Fulham is shown a yellow card for simulation after going down again looking for a free-kick.

Colchester head coach Hayden Mullins knows his side will need to be at their best if they are to upset Wigan.

The U's are 18th in League Two after an inconsistent season and meet a Latics side second in League One, but only behind leaders Rotherham on goal difference.

"We're up against a good side, we know that. We know it will be a tough game but the onus will be on them," Mullins told BBC Essex.

"I think we have earned the right to go in with a bit of confidence, really enjoy the game but attack it at the same time."

Colchester and Wigan meet for the first time in the FA Cup today - and play each other for the first time in any game since March 2016 in League One.

It's the first time the U's have been in the second round since that season - although they have gone on to reach the third round seven out of the last eight times they have reached this stage.

Wigan, meanwhile, have lost just one of their last 13 FA Cup ties against a side from a lower division - last season against Chorley - although they have won only one of their past seven visits to Colchester.

And we're off and running in Essex.

The first sniff of an opening for Plymouth as Joe Edwards is played into the box.

His shot skids just the wrong side of the post - but it wouldn't have counted in any case as the flag belatedly goes up.

In the build-up to this afternoon's second round tie, Colchester's players have been warming up wearing shirts bearing the name and number of Wigan striker Charlie Wyke.

The former Carlisle and Sunderland forward was released from hospital this week after suffering a cardiac arrest in training, and was thankful to Latics boss Leam Richardson for saving his life by performing CPR.
