Cambridge United have signed former Norwich City defender Michael Spillane on a one-year deal.
The 24-year-old, who can play at right-back, central defence or in midfield, was released by Southend in the summer.
He left Dagenham & Redbridge for the Shrimpers in January, and played nine times, but the Essex club declined to activate his 12-month extension.
"I had other offers on the table, for more money, but I really believe in the project [here]," he said.
"The fact that it's a new challenge appeals to me so it all meant there was only one choice - that was Cambridge United."
