Having seen off Plymouth, MK Dons and Brighton, the Royals now have to make a very difficult trip to the Emirates - one of the club's biggest cup games in recent years.
Because of that, information about the match and specifically ticket sales has been eagerly anticipated. Below, we've answered the questions you (probably) have.
When is the game taking place?
7.45pm on Tuesday 25th October.
Where will the match be played?
The Emirates, duh.
How many tickets have Reading been allocated?
2,922 in the South End Lower Tier initially, but there is a 'sizeable additional allocation available' depending on how fast tickets go in the first week they're on sale.
Ie, if it's clear that loads of people want to go, we'll ask for more seats.
How much are tickets?
£10 for adults and £5 for concessions (16 and unders, 65 and overs).
Massive kudos to the powers-that-be for keeping prices so low. Cup football is typically cheap anyway, but it's still a big boost for anyone wanting to make a trip to one of English football's best stadiums.
When do they go on sale?
For season ticket holders, it's Monday 3rd October at 9am. There's currently no information on availability for regular member card holders. Naturally, that'll depend on how many tickets the season ticket holders buy.
Damn, I can't go. Will it be on Sky?
Nope. You'll have to put with the Manchester derby and Liverpool vs Spurs for coverage of the fourth round of the League Cup.
