Roberto Martinez has ruled Darron Gibson out of the rest of the season after he underwent tests on his damaged metatarsal. The Everton midfielder was hurt in the 2-1 win over Queens Park Rangers last month but Martinez was hopeful that Gibson would be able to play some part in the final seven matches of the campaign. Now, though, he has been forced to admit defeat with that plan. It is a blow for the Everton manager, whose side have staged a mini-revival in recent weeks, but he insists there is positive lining in that Gibson, who missed almost all of Martinez's first campaign with cruciate ligament damage, does not require surgery. Everton midfielder Darron Gibson will not play again this season after damaging his metatarsal . Everton manager Roberto Martinez expects Gibson to return to pre-season in the best possible shape . Martinez now expects the former Manchester United midfielder to return to pre-season in the best possible shape and maintains he has a crucial role to play in Everton's future. 'I don't think we are going to see him this season,' said Martinez. 'But I am not too worried about that. It is a tricky injury because if you don't heal it properly, it could come back. We need to make sure he is 100 per cent. If he is fully fit for pre-season, that would be fantastic. 'Darron has been through a lot. We don't have another player like him in the squad. We are trying to support him. He can add that calm feeling, he has shown his worth and what he is capable of adding. But it is tough, I won't lie. It is devastating for him. 'We just have to look at the positive that he doesn't need surgery, as at one point it looked very likely.' Martinez, meanwhile, has admitted Romelu Lukaku is only '50/50' to be involved in Saturday's trip to Swansea owing to a hamstring injury. The Belgian international, whose future on Merseyside has been the subject of speculation, has only been making slow progress. Everton striker Romelu Lukaku is only '50/50' to be involved against Swansea due to a hamstring injury . We will give him as much time as we can,' said Martinez. 'It is still 50/50 as to whether he will make it. We need to make sure he is 100 per cent before we put him on the football pitch again. It is not a big problem but we do not want to take any risks with him. 'But we are very strong in terms of numbers. The squad is developing really strong competition for places. We want everyone fit and available. The squad is big enough to cope with these problems. After the demands of Europe, we have fully focused on the league. 'We have been able to cope with the mental fatigue. I do feel that we will learn and the focus is getting good momentum in the season. There are lessons to learn. We are now a more mature team. It's been a tough season and we will learn our lesson. We want to continue our momentum.'
