Swindon captain Paul Caddis has signed a one-year contract extension to keep him at the County Ground until 2014.
The 24-year-old defender, who joined the club from Celtic in August 2010, made 50 appearances for Paolo Di Canio's side last season on their way to winning the League Two title.
His existing deal was due to expire next summer but the club have decided to exercise an option to keep the Scot in Wiltshire for a further 12 months.
Caddis told BBC Wiltshire: "It's something I thought would happen. I'm happy here and the club are happy to have me. The manager likes me and people behind the scenes have complimented me on the way I've put myself about. It's a bit of security for myself and I just hope by the end of my contract I'll be playing in the Championship with Swindon."
"I'm still relatively young and to captain a senior side is something special. It's something I enjoy as I like the responsibility and I thrive off it. Thankfully the manager has seen that in me."
Caddis, who has made 92 appearances for Swindon, started the season as vice-captain but was promoted in October after Oliver Risser was stripped of the armband by Di Canio.
