Brentford now know all 23 of their 2014/15 Sky Bet Championship opponents.
The Bees won promotion more than a month ago and will be playing in the second tier for the first time since 1993.
The Championship line-up was completed yesterday when Rotherham United won the Sky Bet League One Play-Off Final.
The Yorkshire side trailed Leyton Orient 2-0 at half time but came back to level and take the game to extra time.
Penalties were required and Rotherham recovered from missing their second kick to win 4-3.
Rotherham joined The Bees and Wolverhampton Wanderers in winning promotion from League One and will play – as well as three teams relegated from the Premier League, Norwich City, Fulham and Cardiff City – in The Championship next year.
Derby County – who lost the Championship Play-Off Final to Queens Park Rangers on Saturday, May 24 – Brighton and Hove Albion and Wigan Athletic, who lost in the Play-Off semi-finals, will also come to Griffin Park next year.
As will the following 14 teams that were in The Championship this season and will not be going up or down:
Reading
Blackburn Rovers
Ipswich Town
AFC Bournemouth
Nottingham Forest
Middlesbrough
Watford
Bolton Wanderers
Leeds United
Sheffield Wednesday
Huddersfield Town
