Derby's Tom Barkhuizen has put in a low cross from the right but, although Nathaniel Mendez-Laing gets to the ball ahead of Bolton keeper Joel Coleman, he can't get the crucial touch to open the scoring.

Mansfield are looking for a fourth but Stephen Quinn's chipped effort goes over the bar.

Bradford boss Graham Alexander looks for inspiration from his bench and makes a change as Kevin McDonald comes on for Liam Ridehalgh.

Blackpool are a goal down at Wigan, with Scott Smith scoring at the far post for the Latics.

Neil Critchley's side could do with coming back into the game, given that fellow play-off chasing sides Oxford and Lincoln are winning their games against Port Vale and Bristol Rovers respectively.

Cheltenham are keeping the match tight at 0-0 at Barnsley, which could help their cause to lift themselves out of the drop zone.

They are on track to cut the gap to safety to four points, given that 20th-placed Cambridge United are losing 1-0 at Reading.

Another enforced change in the first half, this time for the leaders.

Kusini Yengi is into the action just after the half-hour with Christian Saydee forced off with injury.

Derby's Curtis Nelson has headed over the bar from a Joe Ward free-kick after a trip on Ebou Adams. The hosts are growing into the game.

Both sides are still looking for an opener and both sides have come very close.

The latest chance coming to Forest Green's Tyrese Omotoye who hits the post with a nice effort.

What a busy game this is!

Posh striker Ephron Mason-Clarke has collected a pass from Archie Collins and lashed an angled strike the wrong side of the post, from his point of view, and into the side-netting.

As close as the leaders have come, Marlon Pack's free-kick from the right wing is met by the head of Colby Bishop but the 16-goal top-scorer can only divert his header to Posh stopper Jed Steer.

Clinton Mola has come close to a second for the Royals, gliding in from the right wing, shifting the ball onto his left foot and whipping a curling shot narrowly over Jack Stevens' crossbar.

Early blow for Derby who have seen forward Dwight Gayle limp off to be replaced by Korey Smith after just 21 minutes at Pride Park.

Ephron Mason-Clark has thundered a shot against the crossbar for Posh after some flowing approach play from the hosts. They are getting closer.

It seemed like Lincoln City had the toughest game of the play-off chasing sides in League One, but Bristol Rovers don't appear to have turned up quite yet.

Lincoln have scored three times in 12 minutes without reply to push themselves up to seventh place in the table.

Joseph Taylor has two goals, following Paudie O'Connor's opener for the Imps.

Oxford are now in sixth - the final play-off spot - as they are ahead at Port Vale, thanks to Ciaron Brown.

This is all at the expense of Stevenage, who as it stands have dropped three places to ninth, with Max Sanders has scoring his first goal for Leyton Orient, who lead 1-0 at Broadhall Way.

End-to-end fare at London Road where Christian Saydee has had an effort blocked for Portsmouth while the home side's Harrison Burrows has fizzed past the base of the post and Joel Randall has fired off-target from a free-kick at the other end.

It has been a lively start at Priestfield Stadium, where two goals in two minutes mean Gillingham and Grimsby Town are level at 1-1.

Grimsby Donovan Wilson scored the opening goal, but the Gills are on level terms after a great moment of control and composure from Georgie Lapslie.

Talking of levellers, Accrington's Shaun Whalley has made it 1-1 against Notts County.

First real chance and Derby keeper Joe Wildsmith has pulled off a fine reaction save to deny Jon Dadi Bodvarsson's point-blank header. Bright start from the visitors in this huge game.
