After applying himself well in pre-season, he made three appearances for Preston in October 2008, but was told by manager Alan Irvine that he would be restricted to appearance from the bench at Deepdale. During his time at Preston he suffered with depression. In January 2009, Jarrett left Preston after negotiating an early release to his contract, and joined League One side Brighton & Hove Albion, signing a contract until the end of the 2008–09 season. Adams lost his job not long afterwards, and new manager Russell Slade brought in his own man in Gary Dicker from Stockport County. It was announced on 12 May 2009, that Jarrett would be leaving Brighton after the expiration of his contract at the end of June 2009.
