LOCK it in.

The details for Carlton’s Round 23 clash with Geelong have been confirmed.

The Blues will end their home-and-away season on Saturday 24 August against the Cats, with the game to kick off at 4:45pm.

To be played at GMHBA Stadium, it will be a perfect test to end the 2019 season for the Blues against the ladder-leading opposition.

In a fixture quirk, the final-round clash will be the first time the two teams meet in the 2019 season.

The two teams met at GMHBA Stadium last season for the first time in 21 years.
