Hibs defender Tim Clancy is off to see a specialist in England for assessment of his ongoing groin injury. It could be that surgery is the only option for Clancy who has missed four of the last five games. In that period, he has only made a truncated appearance against former club Motherwell, when he was substituted midway through the second half. Manager Pat Fenlon said: "We've rested him on the advice of the physios. It's improved it, but it hasn't improved it enough. It's a deep-rooted muscle, rather than a main groin muscle so difficult to treat because it is so deep. That's why we've sent him away to a specialist. There's a few options in relation to the injury he has, so we want to make sure we take the right option. There's rest, there's surgery, there's an injection. We've rested him a little bit now and there has been an improvement, but dramatic improvement, we need to look at other options." With Clancy out and Hibs captain James McPake (back) doubtful again for Saturday's game with Aberdeen Fenlon's men may be pushed to extend their unbeaten run at home. Key to the run and Hibs' present position in second place in the SPL has been the performance of top-scorer Leigh Griffiths. Fenlon has no update on whether Hibs will be able to hang onto Wolves striker Griffiths, left-sided Manchester City defender Ryan McGivern and Motagua midfielder Jorge Claros beyond their current loan spells, which end in January. Fenlon is still looking for players to strengthen the squad and is realistic that if players leave, he will have to find replacements. He said: "We're working away to hold on to our better players. When we have any news, whether it's good or bad, we'll let the supporters know as quick as possible."
