Hibs' Callum Booth is rated doubtful due to illness. Derek Riordan is set to start up front in what could be the out-of-contract striker's final match for Hibs, while goalkeeper Mark Brown is poised to be restored in place of Jakub Divis. Francis Dickoh is available following a ban, but Ian Murray, Danny Galbraith and Michael Hart (rested), Graham Stack (shoulder) and Matt Thornhill (knee) are out. Aberdeen have no fresh concerns ahead of Saturday's game which could mark the final Dons appearance for Jamie Langfield, Sone Aluko and Chris Maguire. The out-of-contract trio are considering offers to stay at Pittodrie, while defender Zander Diamond, whose contract also expires this summer, remains a doubt with a hip problem and may already have played his final match for the Dons. Paul Hartley, who has been struggling with a knee injury, today announced his retirement, while Fraser Fyvie is in contention to start after two substitute appearances since recovering from a cruciate knee ligament injury. Hibernian (from): Brown, Thicot, Hanlon, Booth, Miller, Palsson, Wotherspoon, Scott, Vaz Te, Sodje, Riordan, Nish, Stevenson, Stephens, Duffy, Divis, Trakys, McCann, Towell, Taggart, Forster, Handling.
