"This year I can't play in England, but hopefully I can go somewhere else, go abroad or something, get a year in, good football, score some goals and then come back next season where nobody can have interference in what I'm doing.
"Because right now they're controlling my life and it irritates me.
"I just want to say sorry to Darlington people, fans and staff, I give thanks to them, and hopefully they can get promoted this season and get back to where they belong."
Began his career at Chelsea - but made one appearance against Levski Sofia in the Uefa Cup
His professional debut came with QPR in March 2001
Knight's 27 goal haul at Brighton is his career best for a single season
Quakers boss Cooper had initially refused to comment on Knight after the 2-2 draw at Bath City on Saturday, but then expressed an interest in trying to resurrect the deal.
However the recent events involving Knight and former club Rushden appear to have shelved the transfer.
Former Chelsea trainee Knight has represented 13 different clubs during his career spanning 82 goals in 288 league appearances.
His most prominent spell came with Brighton between 2003 and 2006, where he netted 30 times in 106 league appearances, including 27 goals in the 2003/04 campaign.
That season Knight also netted the winner from the penalty spot in the then Division Two play-off final against Bristol City at Cardiff's Millennium Stadium.
