In November 2008, Blackburn announced that Jansen would return in a casual agreement to help regain fitness in a bid to have one last go at reclaiming the promising and glittering career he once had in professional football. Having trained with the club for two months, he left Brockhall with the arrival of new manager Allardyce. Jansen was present at the club's Premier League game with Newcastle United when he also featured in a pre-recorded half-time lottery draw broadcast on the club television station as part of the half-time "entertainment".
