Luton progressed to the FA Cup third round after a 1-0 replay win over fellow League Two side Bury at Kenilworth Road.Winger Luke Rooney scored the only goal moments after half-time when his cross deceived keeper Shwan Jalal and went straight into the bottom corner.A quiet opening period saw Bury's Danny Mayor thump a half volley wide while Luton defender Fraser Franks' deflected header hit the outside of a post and went behind.Town were dangerous from free-kicks at times, Luke Wilkinson nodding over the top from Andy Drury's delivery.The hosts' leading scorer Mark Cullen diverted Rooney's goalbound shot off target and was then inches wide with a low daisycutter.After the break Luton got what turned out to be the winner when Rooney's low cross was missed by Cullen but nestled into the net.Hatters were close to a second as Whalley's delivery was just beyond Cullen who clattered into a post.Full-back Scott Griffiths was then denied by a wonderful Jalal save while Town could have won by more with Ross Lafayette and Michael Harriman seeing shots repelled by Jalal.However, Bury's Nathan Cameron missed a sitter in the final seconds, putting a free header straight at Mark Tyler.
