Oxford are through to the FA Cup fourth round after beating MK Dons on penalties at Stadium MK.
The game finished 1-1 after extra-time, after Aaron Collins put the Dons ahead before Will Lanskhear equalised for the visitors.

One noteworthy spectator was Matt Bloomfield, who was announced as Oxford head coach a few hours before kick-off. He watched on with interim boss Craig Short taking charge.
In the 34th minute, the Dons took the lead. Collins bundled the ball in from close range after Oxford failed to clear Dan Crowley's corner.
