Premiership defender Harry Taylor is likely to continue his career with the Cats into 2020, with both parties agreeing in principle to extend his time at Geelong into a 13th season.

The 33-year-old will still need to agree to terms before finalising his decision, but there is a willingness from both parties to discuss an extension.

Taylor, who played in the 2009 and 2011 premierships with the Cats, has been a mainstay in defence during his 261-game career and played 24 games in 2019 to prove his worth after an injury-riddled 2018.

He was given big jobs in the finals series as he took on a key defensive position, but he was a strong contributor throughout the season with Mark Blicavs alongside and is highly regarded for his mentoring and guidance of the club's younger defenders.
