The 25-year-old was left without a club after the Lilywhites were kicked out of the Welsh Premier League amid crippling financial problems and, by his own admission, the Scunthorpe-born midfielder had grown disillusioned with the game.
Now, wingman Kirk has rejoined Boston United and made his second start for the Pilgrims in last Saturday's 2-1 defeat at Guiseley.
"These have been my first four games in 13 months, I got 75 minutes under my belt against Guiseley and feel good ahead of Eastwood on Boxing Day," Kirk says.
"I want to kick on now because my fitness is getting better all the time."
A former Manchester City and Scunthorpe trainee who was a national award winner in the Nike Freestyle Soccer tournament in 2003, Kirk had his first spell with Boston before joining Stamford AFC of the Unibond First Division in 2008/9.
After being named player of the year, he attracted the attention of Sheffield United and then joined Macclesfield Town, making his debut in a Carling Cup tie against Leicester City.
He was allowed to leave the Moss Rose in August 2009 and join Rhyl on-loan, a move which was made permanent the following January, scoring three goals from 24 (+3) Welsh Premier appearances.
