Ten-men Barnstaple Town came away from Edgar Street with a point after holding the league champions to 2-2 draw.
Liam Gregory picked up a second yellow before half time after a late challenge on Jamie Molyneux.
Ryan Turner put the visitors ahead in the 31st minute, before two goals in quick succession in the second half from Joel Edwards and John Mills put Hereford ahead.
But the Bulls couldn't hold onto the lead as Turner scored his second in the 88th minute.
More later.
