Barnsley's current strike-force have mustered just THREE league goals between them this season and Davey has taken the gamble on Macken's Championship pedigree to change that.
Ironically Macken is set to make his debut against the side where he made his name on Saturday - Preston North End.
Macken hit 79 goals in 229 matches for the Deepdale side between 1997 and 2002 after coming up through the ranks at Manchester United.
This form earned a big £5m move to Manchester City in February 2002 where he helped the Blues to romp to the First Division Championship, scoring twice against Barnsley in a 5-1 win at Maine Road in front of the SKY Cameras.
He repeated the feat two years later when City crushed The Reds 7-1 in the Carling Cup. He scored only 5 Premier League goals for City however with one coming in the Manchester derby and moved to Crystal Palace before joining Ipswich Town on loan.
Reds fans will probably remember his infamous tantrum last season when he repeatedly kicked the bench after being substituted in our 1-0 triumph at Oakwell.
He joined Derby County in the latter stages of the season as The Rams won promotion to the Premier League but is yet to feature in their campaign.
In total Jon Macken has made 343 career appearances for five clubs scoring 91 goals (5 coming against Barnsley). He has 1 cap for the Republic of Ireland
