Preston had some good chances before the break and now it is the home side who are in the ascendancy.

Jason Kerr's header from close range deflects wide.

Luton are knocking on the door of an opening goal against Birmingham but they haven't quite got that killer instinct to put the ball away.

Carlton Morris has a good curling shot at goal, but it doesn't quite bend enough to creep inside the post.

Grimsby were promoted back to the EFL through the play-offs last season, thanks to a series of late goals.

They might need more today as they trail at Leyton Orient - George Moncur with a debut goal from the penalty spot.

Tom Bradshaw thinks he's made it 2-0 for Millwall as he finds the back of the net with a thumping volley from range.

But the linesman has other ideas and raises his flag for offside and it's scratched off the scoresheet.

Is this the start of a special Stockport comeback?

Antoni Sarcevic bundles home and the Hatters are now 3-1 down at home to Barrow.

Elsewhere, Kane Hemmings has levelled for Tranmere against Stevenage.

Nearly an equaliser for the away side.

Tom McIntyre looks to slide in at the back stick but Tangerines goalkeeper Liam Grimshaw is in the right place to deny him.

Josh Bowler has looked very lively for the home side so far and he hits the post with a crisp strike.

The rebound comes back to him but he can't sort his feet and Royals goalkeeper Joe Lumley gathers.

The new five substitutions rule across the top four divisions means we'll probably be seeing a lot more of this from managers who are unhappy with their sides at half-time.

Peterborough boss Grant McCann has made a triple change - former League One golden boot winner Jack Marriott among those coming on - with his side trailing 2-0 at Cheltenham going into the second half.

Max Aarons rushed in really and sold himself a little bit.

Nobody came out to close the ball down - it was a good strike but went through three or four players.

Poor defending, poor shutting down - you have to shut him down.

We're back under way on this opening Saturday of the EFL season.

The first red card of the new EFL season has gone to Doncaster forward Lee Tomlin, against Bradford.

The veteran picks up what seems to be two very silly yellow cards in the space of less than a minute.

Still goalless for now.

Hull ramp up the pressure right on the edge of half-time, as Oscar Estupinan breaks in a one-versus-one with Dan Bentley but the Robins' keeper comes out on top.

The Tigers then win a corner and the Bristol City players literally throw themselves on the line to preserve their 1-0 lead, right before the referee blows his whistle.

Two great saves from Wigan goalkeeper Ben Amos to deny Troy Parrott and then Emil Riis on the rebound.

Riis then hits the crossbar from Robbie Brady's corner.

The away side will not want the half-time whistle to go.

It's stagnated a bit. Neither side is taking a grip of the game. It's getting a bit scrappy with very few chances as we approach the half.

Matt Pollard: Wycombe 3-0 up get in! Fingers crossed the Wanderers will get more.
