OXFORD United’s Carabao Cup clash with Swansea City will take place on Tuesday, August 9.
The U’s welcome the Sky Bet Championship side to the Kassam Stadium in the first round of the competition.
Prices have been reduced in all areas of Grenoble Road for the 7.45pm kick-off, with adult tickets costing £15.
The game falls between United’s opening Sky Bet League One home match against Cambridge United on August 6, and the trip to Bristol Rovers four days later.
The U’s and Swansea are both former winners of the competition, lifting the trophy in 1986 and 2013 respectively.
They last met in the Emirates FA Cup third round in January 2016, when United pulled off a famous 3-2 victory over a side then playing three divisions above them.
Swansea finished 15th in the Championship last season.
