Oxford United were taken to a replay by Barrow in the FA Cup.
Jamie Cook gave them a ninth-minute lead in their second-round tie at the Kassam Stadium.
But the game turned on an incident on 42 minutes when Luke Foster was sent off for pushing Robin Hulbert in the back, and Andy Bond equalised from the spot.
Ten-man United were unable to force in a second goal, so they must try again at Holker Street on Tuesday week.
Their lead at the top of the Blue Square Premier was cut to two points as second-placed Stevenage won 1-0 at Salisbury.
