Christian Kalvenes timed his first Burnley goal to perfection with an 85th-minute winner to plunge Blackpool deeper into the relegation mire.The Norwegian left-back burst into the box to sweep a low drive past keeper Paul Rachubka to settle a dire game.Fierce winds made proper football near impossible, and play only continued after the two managers and match officials consulted in the 22nd minute.The tie could have ended 2-0 had Martin Paterson scored when through late on.Blackpool caretaker boss Tony Parkes: "It could have gone either way in those conditions. We battled away well and I thought we should have had something from the game."We should have had a penalty in the first half but the referee was that concerned with abandoning the game that he lost concentration and missed things."He kept coming over to the sidelines to ask myself and Owen Coyle to agree with him to abandon the game. The conditions were okay and it's very rare you abandon a game because of wind and I thought it was very strange the referee wanted to do that."I don't think he had his eye on the ball all the time and that cost us a win, never mind a point."Burnley manager Owen Coyle: "It was a must-win for us tonight and the players I brought back into the side - Kevin McDonald, Clarke Carlisle, Christian Kalvenes and Chris Eagles - all played their part."This wasn't a typical Burnley performance, but it couldn't be in those conditions."But it was a really brave performance, full of courage and desire and it keeps us up there."Blackpool: Rachubka, Coid, Barker, Baptiste, Crainey, Taylor-Fletcher (O'Donovan 60), Jorgensen, Adam (Owens 82), Vaughan, Campbell, Ormerod (Blackman 65).
