Tonight it was confirmed the 'Light My Fire' singer - who was partnered with Karen Clifton - is departing the dancefloor for "personal reasons".
"I leave with joy in my heart that I have been able to take part in one of the most loved shows on British television," he said in a statement.
"I am so grateful to everyone who works on Strictly from the lighting designer to catering to the production team."
However, although the show is now an extra contestant down, Will will not be replaced in the line-up.
The BBC confirmed to Digital Spy that it's business as usual, with the next boot-out taking place this weekend.
"The series will continue as planned, with elimination every week until the Grand Final," a show spokesperson said.
"There is not and never has been a backup celebrity on standby."
The news will disappoint fans of Tameka Empson, who had called for her to be reinstated following her controversial elimination in Sunday's episode.
Twelve couples remain in the competition, which continues this Saturday at 6.30pm on BBC One.
