Chesterfield have signed former Leyton Orient defender Terrell Forbes on a one-year deal.
"Terrell can play in a number of defensive positions. He is a player I wanted to sign a couple of seasons ago," said manager John Sheridan.
The 30-year-old had previous spells at West Ham, QPR, Grimsby Town, Oldham Athletic and Yeovil Town.
For the last two seasons he has been a regular at Orient, making 73 appearances before being released.
