Oxford defender Michael Duberry scored two own goals and a late leveller for his side as they drew with Hereford.
The U's led when Jon-Paul Pittman scored from outside the penalty area but Duberry deflected Joe Colbeck's cross into his own net.
Oxford were pushing for a winner, with Simon Heslop forcing a good save, but the Bulls looked set for the points when Duberry headed into his own net.
But the veteran saved a point when he fired home from inside the box.
Duberry said on Twitter afterwards: "Wow. Didn't expect an afternoon like that. Scoring the imperfect hat-trick - left foot (OG), header (OG) and right foot. Thanks for all the positive tweets and thanks for the negative ones - as through positive thinking I'll turn a negative into a positive."
VIEWS FROM THE DRESSING ROOM
Oxford United manager Chris Wilder told BBC Oxford:
"I'm happy that we didn't start lumping it and smashing it forward like other clubs do.
"We've got a principle about playing here at the club. We've created enough chances. We should have been out of sight at half-time.
"They've sat so deep, it's ridiculous. I'm not going to lump it. If they [fans] want to see that, they can go somewhere else."
Hereford manager Jamie Pitman told BBC Hereford & Worcester:
"I would have said in the last 20 or 25 minutes that we would have taken a draw.
"But you get a little bit disappointed that it came down to just that one chance right at the end.
"I am slightly disappointed by ultimately I am delighted with a point as they are a very good side."
