Fulham became the third and final team to join the Premier League after losing 2-0 to Burnley on Monday.
Scott Parker created the feeling of drowning in Craven Cottage, where Ashley Weswood's first half-goal and in his form Chris Wood - who was his 50th for the club - caught him right away. He agreed to return to the championship.
This is the first time in the history of the Premier League that all three matches are left.
Matej Vaidra put Westwood up for the opener after 35 minutes and Wood was clinically out of his eighth goal until he released a volum shell shock before the break.
The Catchers have scored just one point in seven games since a stunning 1-0 win over Liverpool in March.
The London club's fortunes were confirmed with three games in hand, as they are 10 points behind Southampton and Brighton and Hove Albion.
After Sean Deutsch's 350th league game took charge of the club, Burnley managed to maintain its high-flying status.
Fulham went down with Rock Sheetsfield United and West Brom, who were knocked out 3-1 in the Arms on Sunday.
The Catechers, who have won just five matches, are the 17th club to go straight down after winning the Championship play-offs earlier in the season.
