Burnley moved back into the Championship automatic promotion places as they beat Oxford at Turf Moor to extend their unbeaten league run to 18 matches.
The Clarets' positive start was rewarded just after the half-hour when defender Michal Helik diverted Josh Cullen's cross into his own net.
Greg Leigh spurned Oxford's best chance to level before the break, while U's goalkeeper Jamie Cummings produced three saves to deny the hosts a late second.
Scott Parker's side move above Sheffield United into second place, on goal difference, and within two points of table-topping Leeds United, having played a game more than both.
