Full-time and it's a vital victory for Exeter City - their first since 26 December in the league - and a hammer blow to Cambridge United's survival hopes.

A tight game between two sides struggling was decided by Josh Magennis' accurate header from a Caleb Watts cross about 20 minutes from time.

The hosts will rue missed opportunities in this one, with Ryan Loft, Josh Stokes and Jordan Cousins all missing glaring chances in front of goal to grab at least a point in this one.

Exeter climb to 16th before our 15:00 games, while United remain deeply rooted to the bottom.

That's it. Matty Stevens' 20th goal of the season takes AFC Wimbledon above Notts County, who started the day in second place but aren't playing today.

Regardless of Bradford's result against Newport later, the Dons - now unbeaten in 10 matches - will end the day in the automatic promotion places.

Exeter look to be seeing this one out rather maturely.

Goalkeeper Joe Whitworth is cautioned for time-wasting after kicking the post with his boots before taking a goal-kick.

We've got around 90 seconds left here.

What an effort from Luke Molyneux, 25 yards out, it can't have been more than a lick of paint wide.

I thought that was in.

Rovers are starting to get the ball into the area now.

Northampton left it too late to join the fray and didn't have enough to truly trouble their Welsh visitors.

Wrexham, meanwhile, collect maximum points and go within one point of second-placed Wycombe, with the Chairboys next up at Crawley in one of our 15:00 GMT kick-offs.

Almost an equaliser for Rovers! Luke Molyneux fires narrowly wide.

An anxious moment for the Dons as keeper Owen Goodman fumbles a cross - but he's able to gather the ball before Salford's Matty Lund can get to it.

Four minutes of added time to play but the home fans have already began to filter out the ground.

They aren't singing about staying up today.

Can't say boss Kevin Nolan didn't warn them.

Six minutes of additional time has been added by the referee. Enough time for a Cambridge equaliser?

Grimsby are going to have a nervy few minutes here, they are going to have to fight hard to keep this lead.

They have been able to keep Luke Molyneux quiet all game until now, a great cross by him.

Things are spilling over now.

Cobblers forward Cameron McGeehan is absolutely furious with the referee with seeing his name in the naughty book after clashing with Max Cleworth.

Both players are given a yellow card for their involvement in the spat that was quickly intercepted before things got out of hand.

Cambridge earn themselves a corner and a low ball is fired in.

It should be dealt with by Exeter but the ball lands at Jordan Cousins, who anxiously swipes at his effort from 10 yards out over the bar and into the stand behind the goal.

You really feel this isn't Cambridge's day in front of goal.

United substitute Dom Ballard's shot on the edge of the box is well blocked by Alex Hartridge.

The hosts have played most of the football in the second half without having that all important killer instinct which Josh Magennis showed about 10 minutes ago.

Into the final 10 minutes and AFC Wimbledon are closing in on a win that would take them into the automatic promotion places. Can Salford hit back?

Doncaster haven't really had any quality possession. They have allowed Grimsby to make this game scrappy. They've only had one corner and one shot on target since the restart.

That's all for Northampton's Ben Perry and Akin Odimayo.

They make way for Jack Baldwin and Tyler Magloire.

Not long later, Wrexham boss Phil Parkinson exchanges goalscorer Sam Smith and Ryan Barnett for Jack Marriott and Ryan Longman.

It doesn't take long for Steven Fletcher to get involved.

The Wrexham substitute heads a ball in the penalty area but it's in-between a set-up for Sam Smith and a shot and thus finds neither target.

Still no sign of a Rovers recovery despite the earlier triple change by boss Grant McCann, who has now sent on veteran striker Billy Sharp as well.

Three away sides leading and just the one home team in front in our early games.

Still about 15-20 minutes or so for that picture to change...
