Boreham Wood FC are threatening legal action against Carlisle United unless the club withdraws claims their players urinated in the away changing room following an FA Cup replay defeat.

League One side Carlisle have written to the FA alleging that Wood’s players urinated on the floor of their changing room at Brunton Park and damaged the door to the home changing room after the ill-tempered first round match on Tuesday, which Carlisle won 2-1 thanks to a 95th-minute winner.

A teapot was also found in the urinal of the away dressing room, though Boreham Wood claim it was on the table when they left to allow Carlisle’s youth side in to use the changing facilities.

Wood issued a statement yesterday angrily denying the urine allegations, insisting the liquid was in fact orange juice spilt by one of their players after the game.

Boreham Wood media manager Grant Morris said today: "Every one of our players is willing to go to court - everybody. This has angered the whole club. We don't want the people of Carlisle thinking this happened."

The club yesterday hit back with their own claims against Carlisle, insisting some home players goaded and swore at the semi-professional away side following the last-gasp winner.

But Carlisle today refused to withdraw the accusations and said they would have nothing further to add on the matter until they receive a response from the FA.

Monday’s replay was marred by ugly scenes at the final whistle as players angrily confronted each other on the pitch.

Speaking after the game, United manager Graham Kavanagh said: “You don’t want to see scenes like that but there wasn’t a punch thrown. There was one or two verbals and a bit of pushing and shoving but I’m pleased our players stuck together and looked out for each other. I’m not going to apologise - these things happen.”

Wood took a shock lead in the 29th minute through a penalty but were denied a 2-0 deficit when a second spot kick was saved two minutes later.

It took United until the 80th minute to level the game before the stoppage-time winner led the heated atmosphere on the pitch to boil over.
