The third tier fixture, initially scheduled for November 14, has been postponed due to international call-ups.

The second international break of the season spans from Monday, November 9, to Tuesday, November 17.

Aaron Ramsey's Yellows currently sit seventh in the league ahead of a Tuesday night clash with second-placed Stockport County.

In a statement, Oxford said: "The club have received notification that at least three of our players will be called up for their countries during the November international fixture window. 

"Any tickets purchased for the original date will remain valid for the rearranged fixture.

"A new date for the game will be confirmed in due course."

Robbie Savage's Peterborough lie within the relegation places, 21st in League One, at present and one point from safety.
