Orr gaffe sends Bluebirds through

The clash of Championship rivals looked set to go to extra-time until 17 minutes from time, when Michael Chopra struck the post and the ball rebounded and hit Bristol City full-back Orr before finding the back of the net.Chopra was a thorn in the Robins' side after coming on as a first-half substitute, and he had several chances to score before playing his part in the only goal of the game.Ross McCormack also hit the crossbar after Orr's opener but a solitary goal was enough for the Bluebirds to set up a home tie with Leicester in the fourth round.The Bluebirds made an encouraging start and McCormack, still searching for his first goal of the season, fired over from 25 yards out after just two minutes.Scotland striker McCormack was in the thick of the action again after 10 minutes but his right-footed effort from just outside the penalty area failed to test Robins goalkeeper Dean Gerken.Liam Fontaine had the visitors' first chance two minutes later when he rose highest to meet Paul Hartley's corner but his header was off target.It was Dave Jones' home side who looked more likely to open the scoring and Gerken had to be alert to keep out a long-range drive from Peter Whittingham.Chopra replaced the injured Aaron Wildig after 31 minutes and the former Newcastle striker made his presence felt straight away.Chopra raced into the penalty area and lined up a left-footed strike which forced the agile Gerken to make a fine save with his feet.And Chopra fashioned another opportunity for himself five minutes before the break but he volleyed over the bar.Nicky Maynard could have made the Bluebirds pay for their wasteful finishing but the Robins' leading scorer also fired over from the edge of the area.McCormack, operating on the left, crossed for Jay Bothroyd but the former Coventry striker headed over the bar.The lively Chopra was once again denied by Gerken after his pace provided him with another sight of goal.But the deadlock was finally broken when Chopra collected Adam Matthews' through-ball and hit a right-footed shot which rebounded off the post and against the unfortunate Orr before rolling into the back of the net.Three minutes later McCormack was cursing his luck when his long-range drive struck the bar with Gerken beaten.Chopra almost finished the tie off with 12 minutes remaining but the impressive Gerken tipped his left-footed effort around the post, however the one goal proved to be enough to put Cardiff through.
