Antoine Semenyo headed a second-half equaliser as Bristol City fought back to earn an FA Cup third-round replay with Swansea after a 1-1 draw at Ashton Gate. The visitors were gifted a 15th-minute lead when Rob Atkinson’s misplaced pass inside his own box was intercepted by Liam Cullen, who squared for Joël Piroe to shoot into an unguarded net. But after being outplayed in the first half, the hosts battled hard to level on 75 minutes when Semenyo netted with a downward header from Andreas Weimann’s left-wing cross. Both sides could have won it in a rip-roaring finale but in the end Swansea paid for not making more of their first-half dominance. Derby comfortably saw off their fellow League One side Barnsley with a 3-0 victory at Pride Park. James Collins opened the scoring from the penalty spot just before half-time before Tom Barkhuizen and Jason Knight also struck for Paul Warne’s in-form side. Derby, unbeaten in 90 minutes in all competitions since October, took the lead in the 45th minute after Matthew Wolfe handled from a corner and Collins converted the penalty. Derby doubled their lead on the hour after Barnsley failed to clear and Barkhuizen fired into the roof of the net from 15 yards. The tie was over in the 79th minute when Barnsley were caught trying to play out from the back and although Nathaniel Mendez-Laing’s first shot was saved, he rolled the rebound to Knight to drive in the third. David Wagner’s tenure in charge of Norwich began with a defeat with Jack Vale scoring the only goal of the game as Blackburn edged past their Championship rivals at Carrow Road, while Stoke’s league struggles were put aside with a comfortable 3-0 victory at Hartlepool. League Two Walsall earned a fourth-round tie with Premier League Leicester after a 2-1 win over Stockport thanks to Andy Williams’s stoppage-time penalty.
