Jason Valentine and son Ethan were special guests at training on Tuesday after taking out the Farmers Union Iced Coffee 'Hard Yards' promotion.

As part of the prize, the pair was invited to train with the Crows team.

A member of the Tea Tree Gully Under-12s, Ethan enjoyed a kick and a catch with coach Brenton Sanderson and also joined father Jason in posing for a photo with the team.

The prizes keep coming for Jason, who will sit in the coach's box for Adelaide's opening round of NAB Cup matches against Carlton and Port Adelaide at AAMI Stadium on Sunday.

Thanks to our Premier Partner Farmers Union Iced Coffee.
