Oxford are still looking for their first league win as Accrington Stanley kept up their record of not conceding in League Two so far this season as they sides played out a 0-0 draw.
James Constable twice went close for the Us in what was the clubs' first-ever meeting.
The Oxford striker had a volley saved by keeper Ian Dunbavin early in the second half and he was denied by another fine stop by Dunbavin nine minutes from time after a terrific run by Alfie Potter.
The match never really took off as a spectacle, with forwards continually getting caught offside.
Accrington, looking sharp after their narrow Carling Cup defeat by Newcastle, were the better team in the first half as Oxford keeper Ryan Clarke saved from Ray Putterill and Sean McConville.
The lively McConville also darted in from the left past two defenders inside the box, only to sky his shot well over the bar.
The Reds finished the game strongly and Johnny Bateson saw a cross-shot fizz past the far post, but it ended as a third goalless draw of the season for them.
