Morabito is one of the feel-good stories of 2014, having returned to AFL football in round 16 this season after knee reconstructions ruined three consecutive seasons for him.
It was 1394 days between his previous outing for the Dockers, the 2010 semi-final against Geelong, and his return as the substitute against Melbourne in Darwin.

Morabito played three matches before being dropped back to the WAFL.
Fremantle coach Ross Lyon said on Wednesday that the former No.4 draft pick's story was extraordinary, and that he remained in the selection frame for the Dockers' September campaign.
"He is a special player for us," Lyon said.
"What he has been able to do has been freakish.
"He's played senior football, he's playing very good football in the WAFL, so we're really excited.
"In the near-term he's still available for selection, but we're really excited about 2015 as well.
"He's an important part of (our) midfield and we aim to build something around Anthony."
Morabito told the Dockers website that he was thrilled to stay with Fremantle for another season.
"It's a strong environment and a strong club culture and I'm really looking forward to progressing my football with the Fremantle Dockers," Morabito said.
"I was fortunate to get drafted at the same time as a lot of guys, and just seeing how blokes like (Nat) Fyfe and (Stephen) Hill have progressed in their short time at the club, it's just something that I want to be a part of.
"I've got a lot of faith in the support staff that have got me back up and playing a full year now. For me it's just another progression from this year.
"I feel like now we're starting to get a lot of continuity and I'm stringing games together and pulling up a lot better. I'm hopeful for a full summer on the track."
