Arsenal will be facing Wolves away on Wednesday at 20:00 GMT in the Premier League.
It is the only league match scheduled in the midweek - but why?
The fixture was originally set to take place on Saturday, 21 March.
However, as Arsenal will be facing Manchester City in the Carabao Cup final, their fixture against Wolves has been brought forward to a week where both teams are free to play.
Manchester City's fixture against Crystal Palace was also set to take place on 21 March, but the fixture has been postponed with a date yet to be fixed.
