Leeds Rhinos star Gary Connolly is fighting to be fit for the clash with his former club Wigan Warriors this Friday. The veteran full back suffered a calf strain in Saturday's Powergen Challenge Cup defeat to St Helens. He will be assessed throughout the week ahead of Friday's Tetley's Rugby Super League encounter with the Warriors at Headingley. Hooker Matt Diskin, who was forced from the field late in the game at Knowsley Road after taking a bang to the shoulder, is hoping to be fit after responding well to treatment. "We have got a few bumps and bruises," admitted coach Tony Smith, who has Richard Mathers ready to step in should Connolly miss out. The Rhinos went into the clash with Saints with a fully-fit squad, with Chris McKenna, Chris Feather and Jamie Jones-Buchanan missing out on a place in the 17.
