York City manager Nigel Worthington was left counting the cost of his side's 1-0 triumph at Portsmouth as Josh Carson and Wes Fletcher both left the field with suspected medial ligament damage.

The Minstermen bagged their fifth straight win in League Two courtesy of a firecracker strike from Michael Coulson after just four minutes.

But extending their unbeaten run to nine games came at a hefty price as Carson was carried off in the 32nd minute, before Fletcher - the man who replaced him - also had to be substituted after being scythed down by Pompey skipper Ben Chorley in the 50th minute.

Chorley was sent off by referee Roger East and it was a tackle Worthington was far from happy with.

He said: "The one on Wes was a bad challenge - there was no intent towards the ball at all. I don't want to see anyone getting sent off, but it was a nasty challenge.

"To be fair, the one on Josh was a good, solid challenge. It just caught Josh on the wrong side.

"It looks like medial ligaments for both. We'll get them scanned on Monday to see the extent of the damage. Then we can plan from there.

"It's disappointing that it disrupts us to lose the two players. But that's the game of football and you've got to deal with it."

Worthington was content to see his side march into the League Two play-offs in the intense atmosphere of Fratton Park.

He added: "I'm delighted with the result. The lads were outstanding. In the second half, we really had to make sure we stayed focused and concentrated to see the job through.

"To be fair, we did it in good style. We limited Portsmouth and I'm not sure they had a clear effort on goal."

Portsmouth languish just one place and three points above the drop zone, but boss Richie Barker was buoyed by the chances his side created as they displayed far more cutting edge than in recent matches.

He said: "If we play like that, we should win more games than we lose. I thought the mentality of the players was fantastic.

"There were positives to be taken out of the game. I don't know what the statistics were, but up until the last 10 minutes when we pretty much threw everybody forward, we created the most chances.

"From most of the chances we had in the first half, which were pretty decent ones, we probably didn't work the keeper enough. But I felt we created more than we have done for a while.

"When we were down to 10 men, it would have been easy to go under. But the lads stuck at it and we deserved something out of the game."
