Wrexham, owned by Hollywood stars Ryan Reynolds and Rob McElhenney, were on the verge of recording an upset win over Championship club Sheffield United before John Egan scored in the fifth minute of stoppage time to force a replay.
In a frantic second half at the Racecourse Ground, Wrexham twice took the lead through Thomas O’Connor and Paul Mullin on either side of a sending-off for Daniel Jebbison, but the Welsh club were pegged back by goals from Oliver Norwood and Egan.
