Jarrett who has failed to impress the last three bosses at Deepdale is set to finally leave the club after nearly three years at Deepdale.
The midfield man impressed early on when he was signed by Billy Davies. Upon missing out in the play offs and the change of manager to Paul Simpson, Jarrett then failed to re-appear as a consistent firt team member.
Jarrett was loaned out on several occassions over the past couple of seasons and it was thought after a good pre-season under Irvine that he might have a chance at first team football. Unfortunately, he has had no actual game time in the League and is now on his way to Brighton before the Summer when his contract would have expired and he would have been a free agent in the melting pot like many other professional players.
