Adelaide stalwart Scott Thompson has penned a new deal with the AFL club, and looks set to see out his career at the Crows.

Thompson, 30, will extend his stellar Crows career until at least the end of next year - and perhaps into 2015 - after deciding not to test the free agency waters.

The former Melbourne midfielder has played 206 of his 245 AFL games for Adelaide, earning a reputation for both his durability and as a ball magnet.

Crows list development manager David Noble said Thompson would continue to play a crucial role at the club.

"Scott has been a consistent performer at an elite level over a number of years," Noble said.

"Scott has an important role to play in our playing group, not only on match day but in a leadership capacity, mentoring our emerging midfielders.

"He showed resilience to play every game this year and we expect him to be a key contributor again in 2014."

Essendon have also moved to secure one of their unrestricted free agents, forward Jason Winderlich, on a new one-year deal.

Winderlich, 28, came off two frustrating injury-filled seasons for an excellent 2013, and has turned his back on attention elsewhere to remain with the Bombers.

"I've been at the club for 11 years now, I barracked for Essendon as a kid and I couldn't see myself playing in anything other than the red and black jumper," Winderlich told the website.

"It was an easy decision, really.

"This year, we played some really good football and proved we're certainly on the right track to achieving success, and I certainly want to be part of our push for a top-four finish next season."
