Cats enter race for Carlton defender Zach Tuohy

Geelong has reportedly entered the race for Carlton running defender, Zach Tuohy.

North Melbourne and Sydney have already been linked with a move for the out-of-contract Irishman, and the Cats are now also rumoured to be interested, according to The Age.

Tuohy is yet to re-commit to Carlton, despite the Blues offering him a three-year contract extension, while the Kangaroos are believed to have tabled a four-year offer to try to lure the 27-year-old away from Princess Park.

Tuhoy, who has played 120 games in six seasons, is the latest in a long list of Geelong trade targets, which include Pearce Hanley, Brett Deledio and Daniel Wells.

However, the Cats, who are keen to add pace to their midfield, will most likely have to free up some salary cap space in order to secure another gun this trade period. The out of form Steven Motlop looms as the most obvious trade bait and could be involved in a deal in the coming weeks.
