Wrexham co-owner Ryan Reynolds was left licking his wounds after joking about his team having negotiated extra goalkeepers for their match against Sheffield United.
The visitors began the game more than 70 places ahead of Wrexham in the football pyramid, meaning it was understandable for the home side to be nervous about the firepower available to Paul Heckingbottom's side. Sure enough, £20m striker Oli McBurnie took just 64 seconds to open the scoring, serving Reynolds an early reminder of his words.
Any suggestion of the floodgates opening after the early opener proved wide of the mark, though. The non-league hosts came back to lead the game twice and were moments away from a spot in the fifth round only for John Egan to deliver a last-gasp equaliser.
