Torquay United have signed former Chesterfield centre-back Aaron Downes on a one-year deal.
The 27-year-old was released by the Spireites at the end of last season and spent the second half of last season on loan at Bristol Rovers.
The Australian played for his country at youth level and made 184 appearances for Chesterfield from 2004 to 2012.
Torquay have been looking to sign an experienced centre-back since Mark Ellis moved to Crewe last month.
"He was going to be a massive product at Chesterfield but has suffered a couple of bad knee injuries," Torquay manager Martin Ling said.
"These have definitely thwarted his career in terms of where he wanted to go and he is looking to rebuild.
"He needs someone to take a punt and that is the right word for a player who has suffered two cruciates, but we're very confident he will be fine.
"He was available for most of last season and I've spoken to a lot of people about him, and all I've heard has been positive.
"I watched him play for Yeovil in pre-season and they wanted to take him, but as a cover player rather than a starter. I've told Aaron I'm looking for a left-sided centre-half and he has played 90% of his football in that position, even though he is right-footed."
