The race for promotion continues this weekend, with Pompey keen to keep the pressure on the top three.
The Blues face a Crewe side low on confidence, having won just two of their past 10 games.
A win for Paul Cook’s men could see them climb into the top three, with third-placed Carlisle (58 points) facing a tough trip to Plymouth (62 points), who sit just a place above them in second.
The Pilgrims’ promotion bid has stalled recently and they are without a win in their last four matches.
Meanwhile, the Cumbrians have lost their last two fixtures against Cheltenham and the Blues.
With a game in hand over Carlsile, a win for Keith Curle’s side wouldn’t be a disaster for Pompey, providing they win their own game against Crewe.
But a draw would seem the most appealing result for Paul Cook’s side, who are now just two points off the top three.
Elsewhere, table-toppers Doncaster (68 points) face a tricky trip to Crawley.
The Red Devils have been in mixed form recently, but on their day Dermot Drummy’s men can be a match for anyone in League Two.
Doncaster themselves have also struggled over the last few weeks, with just one win in six, meaning the Sussex side will fancy their chances of an upset.
Hot on Pompey’s tails in fifth are Luton (54 points), who face a trip to Huish Park to face Yeovil.
The Glovers are on a frustrating run of form, and are without a win since beating Plymouth on January 31.
Since then they’ve drawn five of their six matches to leave them in 17th place.
Luton, meanwhile, will be full of confidence, having drawn their past two league matches against the top two.
Currently in sixth sit Exeter on 54 points.
Paul Tisdale’s side are also on the road, with a long trip to Hartlepool next up.
Turn the clock back a month and the Grecians were the division’s form side with seven wins on the bounce.
But February proved to be tough for them and they have won just one in their last five.
With Exeter stalling, the side currently topping the form table are Stevenage (52 points).
Darren Sarll’s men are unbeaten in their past seven – six of those being wins – and they will be hoping to continue their good run this weekend against Notts County.
The Magpies have been steadily improving under new manager Kevin Nolan, and three wins in their past five have guided them to the relative safety of 19th place.
Further down the table, it couldn’t be much tighter, with just eight points seperating eight teams from seventh to 15th.
Of those sides, the games to look out for are Mansfield (51 points) taking on an in-form Cheltenham side, Colchester (50 points) travelling to 12th-placed Cambidge (46 points), and 10th and 11th-placed Grimsby and Wycombe (both 47 points) going head to head at Adams Park.
