Adelaide defender Alex Keath has been traded to the Dogs, after negotiations seemed to stall on Wednesday afternoon.

The Bulldogs have handed pick 45 and a 2020 second-round pick to the Crows, with Keath heading to the Kennel along with the Crows' 2020 third-round selection.

Keath has played 30 games across three seasons for the Crows, including 18 this year.

The 27-year-old was one of the Crows' most impressive defenders this season.
