In an incredibly rare feat, the three teams promoted from League One last season all came straight back up after dropping out of the Championship!
This means that Wigan Athletic, Blackburn Rovers and Rotherham United all regrouped and rectified their relegation from the second tier at the very first attempt, and will be returning to face the Royals in 2018-19.
Read on as we take a look at what Reading fans can expect when these three sides all return to play Championship football from August.
Ground: Ewood Park
Manager: Tony Mowbray
With Rovers struggling in February 2017, Tony Mowbray was brought in as manager to try and help the club to safety in the Championship.
While he was unfortunately unable to spare Rovers the drop, becoming the first champions in the Premier League era to drop to the third tier in the process, Mowbray stayed at the helm at Ewood Park and quickly assembled a team that would be immediate challengers for the League One title.
The arrival of highly-rated attacking midfielder Bradley Dack from Gillingham proved a shrewd signing, with the playmaker scoring 18 times on his way to winning the club's Player of the Season award.
There's also a Royal connection among the Rovers squad, with Dominic Samuel having joined the Ewood Park outfit permanently last summer.
Mowbray's men will be hoping to make an immediate impression upon their return to the Championship, having been promoted automatically along with Wigan.
Nicknames: The Millers
Ground: New York Stadium
Manager: Paul Warne
Something of a yo-yo club since the turn of the century, Rotherham have played in all three EFL divisions in at least two separate spells since 2000. They return to the Championship after a hard-fought play-off campaign in the third tier.
The Millers saw off a battling Scunthorpe side across two legs in the semi-finals, before taking on Shrewbury at Wembley at the end of May.
Paul Warne's squad went the distance against the Midlands outfit at the national stadium, with an extra-time winner from centre-back Richard Wood sealing an immediate promotion back to the Championship.
The Royals lead 21-10 in the all-time head-to-head between the two sides, with the last campaign with the clubs in the same division seeing a league double for Reading - something which Paul Clement will be hoping to repeat when they meet again in the upcoming campaign.
Nickname: The Latics, the Tics
Ground: DW Stadium
Manager: Paul Cook
Last but not least, the League One champions. After going down from the Championship in 2016-17, manager Paul Cook was able to keep a core of his squad together and put together a challenge for the league from the off.
Such was their dominance throughout the season, the Royals' 106 point league record even looked (briefly) under threat from Cook's squad.
Nonetheless, they won the league eight points shy of equalling our record and enjoyed some memorable highlights along the way, including one of the shocks of the century in the FA Cup by beating the mighty Manchester City in the Fifth Round.
The goal on the night came from the combustible Will Grigg, after England international Fabian Delph had received his marching orders towards the end of the first half.
Cook and the Latics will come back into the division in the hopes of making immediate progress towards a possible return to the Premier League.
