Jamie MacDonald and Ryan Stevenson agree pay cuts at Hearts It's imperative that we get more money in in the next two weeks. If we don't, more players will go and the club might not be here. Hearts owe £25 million to Lithuanian companies UBIG and Ukio Bankas. Both firms were formerly controlled by ex-Hearts owner Vladimir Romanov, but UBIG are now waiting to be put into administration after its assets were frozen, while Ukio Bankas will soon be liquidated after a Kaunas court declared it insolvent. The bank, however, has a floating charge on Tynecastle and other club assets as security for the £15million it is due, leading to fears that the stadium could be sold off to repay its own debts. It was the threat of court action over a partially-paid £100,000 tax bill, however, that sparked the decision to place the club into administration. BDO on Thursday urged supporters to buy 3,000 season tickets in the next 14 days to plug an immediate funding gap of up to £750,000. Club directors had cited slow sales - Hearts had only hit 70 per cent of last season's 10,000 total - as they ran out of money to pay players and Her Majesty's Revenue and Customs. Hearts fans kept the club afloat last season by buying more than £1 million of shares and Locke - who only replaced John McGlynn as boss in March - appealed to the fans to dig deep once more. He said: "We need to make sure the club survives. We need to make sure we can get people to buy season tickets. If we can do that, we have a chance. The fans have backed us very well over a number of years and we are asking them to do it once more in difficult circumstances. But I have no doubt the fans will back this club 100 per cent. I saw how they rallied last year. I'm a fan myself. I've got three daughters and maybe one day they will get married and have grandkids. I want them to come here and watch the team. Hearts say they have sold an extra 500 season tickets in the 24 hours since administrators urged fans to rally to the stricken club's cause. The club wrote on their official Twitter account on Friday evening: "Ticket Centre reports 500 STs sold in 24 hours! What an effort! Keep going folks. Fans on the Jambos Kickback supporters' website also raised £13,000 through donations on Friday. The manager also paid tribute to the actions of Stevenson and MacDonald in agreeing to take only partial payment of their wages. He said: "That's a bit of positive news, especially for myself. It's a magnificent gesture from the two players and they are the type of players we want at our football club. We have all made sacrifices over the last few days and now we just hope the fans can do the same. Hearts will start next season with minus 15 points after triggering a Scottish Premier League punishment by going into administration. They have also been issued with a transfer embargo after failing to pay staff last Friday. But Locke, who has also gone without pay, insists he will still do everything he can to help the club. "I'm not getting paid any money right now but all my friends and family are buying season tickets," he said. I'll be doing everything I can because I'm the same - I'm a fan and want this club to survive. None of us at the club are getting paid right now because the club has no money. We need to get money in and we can do that, we have a better chance. The transfer embargo has also cost the club the chance to sign Scotland defender Danny Wilson on a pre-contract from Liverpool, with Locke confirming: "Danny is a Liverpool player until June 30 but obviously we have got a transfer embargo now so we can't sign him. I'm losing out on a fantastic player that I would have loved to have built my team around. Hopefully if everything works out, you never know, he might be back here one day. BDO also confirmed that three Lithuanian directors - Roman Romanov, Sergejus Fedotovas and Vitalijus Vasiliauskas - have been sacked. Celtic have secured the signing of Holland Under-21 defender Virgil van Dijk. The centre-back has signed a four-year contract after Celtic agreed a deal with FC Groningen reported to be worth up to £2.5 million. The 21-year-old arrived in Glasgow for talks on Thursday and leaves Groningen two years before his contract was due to expire. Van Dijk, who follows 22-year-old Portuguese forward Amido Balde in joining Celtic this summer, said: "It feels very good and I'm very excited to be here. Celtic is the biggest club in Scotland and they also play in the Champions League. They're a fantastic club and when Celtic came in for me I was so excited. Everything here is good so I can't wait to get started. I hope to play many games for my country in the future but first of all I want to make things happen here. Asked what he will bring to Neil Lennon's double-winning side, Van Dijk said: "I'm a strong defender and I'm good in the air, but I also like to play football on the ground, and I hope that we'll do even better than we did last season." Kilmarnock have escaped punishment after being found guilty over failing to ensure former manager Kenny Shiels complied with Scottish Football Association protocol. Shiels was found guilty earlier this month of bringing the game into disrepute after he claimed in a BBC Scotland interview that Celtic had "massive influence" over disciplinary hearings, describing them as "the monster of Scottish football." Shiels was found guilty of breaching two SFA rules; bringing the game into disrepute and failing to act in the best interests of the game by calling into question the judicial panel, and questioning the integrity of another member club. He was subsequently banned for four games with two of those suspended until the end of next season. However, Shiels left the club by mutual consent just days later, a move that came as little surprise given Killie had been debating his future because of their ninth-placed finish in the Clydesdale Bank Premier League as well as his outspoken media comments. The club were also convicted of failing to ensure that Shiels complied with SFA protocol but they announced today there would be no punishment following a disciplinary tribunal. A statement released by the Scottish Football Association said: "The panel took account of all the mitigation put forward on behalf of Kilmarnock FC and concluded that no sanction should be issued in this case." The Pars Supporters' Trust has urged their mystery rival bidders for administration-hit Dunfermline to make their identity known. Pars United, which the trust is part of, submitted an offer before Tuesday's deadline along with an unknown bidder, who has enforced their right to confidentiality. Fans rallied to keep the club alive after owner Gavin Masterton called in administrators in March with the club more than £8 million in debt and were unaware of rival interest until recently. Drew Main from the Pars Supporters' Trust said: "The apparent desire of those behind the second offer to the club's administrator to remain anonymous is a mystery and is causing not just consternation but also causing increasing concern amongst the wider fan group." Ross County have signed Dutch winger Darren Maatsen. The 22-year-old arrives from Dutch second-tier side Excelsior and is set to be among a number of players from Holland arriving in Dingwall. County will also confirm a deal with 25-year-old midfielder Melvin de Leeuw when his contract with Cambuur expires.
