Former King's Lynn joint boss Kevin Boon last night admitted it was a 'huge wrench' to leave The Walks as a result of an internal club dispute involving centre-back Paul Cousins.

Town officials issued a statement clarifying Boon had resigned, following what they termed a 'fall-out' with the ex-Wisbech captain which came to a head after Lynn's weekend 4-2 FA Cup win over Quorn.

Fellow joint boss Gary Setchell will now be in sole charge for tonight's UCL Premier Division trip to Deeping Rangers after Boon called time on his second spell at the town's senior football club.

'It is a huge wrench to leave the club again when things were moving in the right direction, but no-one is bigger than this football club – and that includes me,' said Boon.

'I would just like to thank everyone who supported me and the people still at the club who are all working to try and build football back up in the town.

'The fans on Saturday at the Seven Sisters End were as loud and as vocal as I have heard for a long while. That is the type of backing this club needs and long may it continue. I respect Gary as a friend and a manager and it goes without saying I wish him all the best, but I cannot accept the situation the way it is at present.'

Town's official statement declined to go into specific details behind Boon's decision to stand down.

It read: 'King's Lynn Town football club is saddened to hear that their joint team manager Kevin Boon has resigned from his position due to a fall out between himself and the player Paul Cousins. King's Lynn Town Football Club feels that it would be unfair to make the nature of the fall-out public, but the club would like to assure fans that any incidents which take place on or off the pitch are taken seriously and will be dealt with once all the facts have been considered.

'King's Lynn Town football club will always support their players, staff and volunteers whenever called upon. Gary Setchell will take over as sole first team manager from Tuesday night and with his focus on winning such a crucial game he has indicated that Paul Cousins will play.'

Boon, along with Darren Bloodworth, guided the former club to a first league title in 50 years when they lifted the Southern League, Eastern Division championship in 2004. The local businessman agreed to return as part of chairman Buster Chapman's bid to win the lease on the council-owned stadium back in January 2010 after the previous club had been wound up in the High Court.

Boon and Setchell guided Town to runners-up spot in the league and the FA Vase semi-finals during the club's inaugural campaign last year. Lynn had made another strong start to the new season – winning six out of their first seven league matches – and secured a home FA Cup third qualifying tie against Midland Alliance Stratford at the weekend.

'I don't believe it is right that Paul should play (against Deeping),' said Boon. 'I made my feelings known, but Setch and Jonathan Chapman have told me he is available for selection and he will play. I can't accept that.

'Luke Thurlbourne and Pat Bexfield have both stepped out of line this season, they were disciplined at the time and they have accepted that. I felt the same should happen in this particular case.'

Saturday's 4-2 cup win over Quorn earned Lynn a fifth consecutive home tie in the competition against Stratford on October 15. Stratford sit currently 18th in the Midland Alliance – the same step five as the Linnets in the non league pyramid – and booked their place in the next round with a 4-2 away win at Stafford Rangers.
