Taylor Walker and his injured knee created a wave of support on social media.
Crows fans led the way with thousands of tributes but the AFL community was also prominent in social feeds.
Here is a selection of some of the tweets from footballers from other clubs - including Port captain Travis Boak, Joel Selwood and Bryce Gibbs - Crows ambassadors, former players, cricketers and others.
