Walsall's David Okagbue picks up the first booking of the game after bringing down Ashley Hay just outside the box.

Ethan Williams' resulting free-kick is comfortably saved by Tommy Simkin.

That's far from ideal.

Jack Currie is involved with Tomoki Iwata and referee Martin Woods doesn't like what he sees from the Leyton Orient man and shows him a straight red card.

It could be a long night for the Londoners now.

The first serious effort on goal comes from the home side and it's Ethan Laird flashing a shot not far wide of Josh Keeley's post.

Both sides feeling each other out at the moment.

A decent response to going a goal down from Cheltenham as both Sam Stubbs and Darragh Power put a couple of crosses into the box but they're unable to find anyone in a red and white shirt.

And Matty Taylor has just had a chance after the ball falls to him inside the area but his strike goes over the bar.

Lee Nicholls is the first goalkeeper called into action as tips over Owen Dale's attempted curler for Wigan.

Boro switch off and gift Stoke front man Nathan Lowe the ball.

He goes forward and cuts a pass through to Million Manhoef but the winger's shot drags wide of the left post.

A couple of early sights of goal for Northampton but Mitch Pinnock's free-kick and a shot from Liam Shaw have both been dealt with by Jackson Smith making his first start in the Barnsley goal tonight.

Stoke goal keeper Viktor Johansson makes a horrible mistake when he drifts closer to the byline than his own boxes and misjudges his touch.

He chests the ball down to Tommy Conway's feet and the keeper sprints back to his line, expecting punishment.

But Conway needs to turn on the ball and when he eventually sets it off for Morgan Whittaker, the winger sends his strike from distance way wide of goal.

A disappointing watch for both sets of fans.

A quiet start at St Andrew's.

Remember these two sides have both taken 22 points from their past 10 games which is promotion form in anyone's book.

Wigan's Dale Taylor is penalised for a foul and referee Ross Joyce deals him a card he won't want - a yellow one.

Northampton have made two changes tonight with Aaron McGowan on the bench while top scorer Cameron McGeehan is out of the squad.

Nesta Guinness-Walker and Jordan Willis get the nod to start.

There's a change in goal for Barnsley as Jackson Smith takes over from Joe Gauci and starts for the first time.

Luca Connell is suspended and Kelechi Nwakali comes into the starting line-up.

After tonight, the picture of the league table will be the true one, so there can be no ifs and buts about Middlesbrough having a game in hand.

After tonight, we'll know exactly where Boro are going into the run in.

They desperately need a win, not a draw.

Jensen Weir drops to the bench for Wigan tonight and there's no Joseph Hungbo.

Into the starting line-up come Babajide Adeeko and Jonny Smith.

For Huddersfield Radinio Balker, and Jonathan Hogg are out and Tawanda Chirewa drops to the bench.

In come Antony Evans, Dion Charles and Brodie Spencer.

Whistles across England and Wales have blown.

Hope you're settled in.

It's time for some football.

It didn't seem possible a few weeks ago but tonight suddenly takes on extra significance for the leaders Walsall whose advantage at full-time this evening could be a whopping 11 points - or down to six.

If the Saddlers lose at Cheltenham then Bradford City can hop into their slipstream with a win at Bromley.

For their part, both Cheltenham and Bromley are putting together a late charge for the play-offs.

It's also a big night at the bottom where Tranmere Rovers against Accrington Stanley has all sorts of connotations not just for them but also at least four others.

One of those is Gillingham who are by no means safe as they host Fleetwood who might perhaps already be preparing for another season in League Two.

Birmingham City make three changes from the team which drew 0-0 a Reading at the weekend.

Scott Wright, Keshi Anderson and Lyndon Dykes are all missing tonight with Willum Willumsson, Taylor Gardner-Hickman and Alfie May starting in their places.

As for Leyton Orient there are also three changes for them as Dilan Markanday, Darren Pratley and Daniel Agyei come in for Dominic Ball, Azeem Abdulai and Randell Williams who are among the substitutes.
