Luton suffered a second successive relegation as their slump from the Premier League to League One was confirmed with a 5-3 defeat at West Bromwich Albion on the final day of the Championship season on Saturday.
After their fairytale rise to the top flight in 2023, the Hatters have plunged into the third tier in the space of just two seasons.
Tom Fellows and Callum Styles both scored twice for Albion and Daryl Dike also netted as the hosts raced into a 5-1 lead.
Millenic Alli's double and Jordan Clark's goal were rendered irrelevant as Luton faced up to their first season in League One since 2018-19.
The Hatters are the first club since Sunderland in 2018 to drop from the top flight to League One in consecutive seasons and only the fourth in the Premier League era after Swindon in 1994-95 and Wolves in 2012-13.
