Vale boss signs up midfielder
The 30-year-old free agent has been on trial at Vale Park and has impressed enough to be handed a deal with the League Two club having been released by Brighton at the end of last season.
Adams, who put his entire squad on the transfer list at the weekend, told the club's official website: "He is hungry to get involved at Port Vale and I know he will be eager to earn his chance here."
Jarrett goes straight into Adams' squad for Tuesday night's home clash against Accrington.
