NEWPORT County AFC will be without influential centre-back Matty Dolan for tomorrow's clash with fellow League Two promotion hopefuls Cambridge United.

The 28-year-old was forced off in the closing stages of Tuesday's 0-0 draw against Carlisle United after a head injury.

Dolan will miss the fixture against the second-placed U's at Rodney Parade (kick-off 12.30pm) through concussion.

He is also a doubt for Tuesday's clash with Crawley in Newport and next weekend's vital trip to Exeter City.

County are already without defender Priestley Farquharson, who will miss the run-in after rolling his right ankle in the 1-0 win against Bolton, but manager Michael Flynn won't rush Dolan despite his importance to the team.

"Crawley is 50/50, I'll need to check with the medical staff," said the boss. "He will be available on the amount of days

"Missing Priestley means that we have had to put Scot Bennett back there and we miss him from midfield.

"It's frustrating because I wanted everybody fit until the end of the season, but it's not to be at the minute."

Flynn is now mulling over his team for Cambridge with the possibility of changing to four at the back with Bennett and Mickey Demetriou at the heart of defence.

He could also plump for David Longe-King in a three but Joe Ledley won't be considered in that role despite the Wales midfielder coming on there off the bench on his debut against Leyton Orient.

"It was a different type of game, the pitch [at Cardiff City Stadium] was unbelievable and we thought that Joe could slot in there because we were fully in control," said Flynn. "Cambirdge will be a completely different game.

Left wing-back Ryan Haynes is available for the Cambridge clash after being sidelined since the start of March with a groin injury, although Aaron Lewis has been in impressive form in the last eight games as his deputy.

Whatever defence Flynn fields will have to be on their game against a United side who are third in League Two for goals scored – they have the best goal difference – and who boast the most potent striker.

Paul Mullin has struck 28 times, a tally that is greater than the entire Southend squad.

"Cambridge have had a remarkable season and one thing that they have got in their team is goals," said Flynn.

"Paul Mullin has got 30 goals [he also scored twice in the EFL Trophy] and that is an outstanding return at every level, it makes a massive difference.

"I like him as a lad; he is a very hard worker and a team player. I want him to have a quiet day against us but he deserves everything he gets.

"He has been around for a while now and is somebody who always wears his heart on his sleeve. He is getting his rewards for hard work."

But with Cambridge also boasting the creative Wes Hoolahan and 12-goal Joe Ironside in their side, County won't be drawn into focusing on Mullin.

"You can't worry about just one player, they have a lot of good players and that is why they are doing so well," said Flynn. "It will be a tough game and we need to be on it.

"It's all the old cliches - we've got to win our battles and the first balls and second balls, we've got to take our chances, we can't make any mistakes. If we do all that then we will win the game."
