Luke Waterfall's winner keeps Lincoln on course for play-off spot

Luke Waterfall headed a last-gasp winner as 10-man Lincoln City secured a dramatic 2-1 victory over Colchester United.The play-off chasing Imps took the lead in the 55th minute through Elliott Whitehouse's penalty after substitute Ollie Palmer had been impeded in the box.However, Colchester levelled on the hour mark through substitute Courtney Senior, who capped a good move after the home side had given the ball away in midfield.Both sides had chances to take the lead with Michael Mandron blazing over the Lincoln bar from point-blank range, while Palmer hit the bar with an audacious effort from outside the box.The Imps were reduced to ten men in the 84th minute when Michael Bostwick was deemed to have denied a clear goalscoring opportunity after hauling down Mandron.Despite that, Danny Cowley's side kept pressing and in the fourth minute of added time another substitute, Waterfall, rose highest to nod the Imps in front and spark scenes of delirium among the 9,000-plus crowd.With Mansfield being held by Port Vale, the win boosted City's hopes of a top-seven finish.
