Heeney five leads Swans past Dockers

Swans star Isaac Heeney showcased his star qualities, kicking five goals as well as producing a mark of the year contender as part of Sydney's 40 point win over Fremantle at Metricon Stadium on Sunday.

The result spoilt Dockers veteran David Mundy's 350th AFL game, Sydney kicking eight goals to two in the second half to run away with the contest.

Injuries were a key part of Fremantle's fadeout, losing captain Nat Fyfe to another shoulder dislocation, Michael Walters (hamstring) and Alex Pearce (concussion) also finishing the match on the bench as the Dockers hopes of finals football in 2021 continue to fade.

In the second meeting between the sides this season following the Dockers two point win over the Swans in round 10, Justin Longmuir's men were sensing a chance of replicating that result early, jumping out to a 17 point lead in the second stanza.

A stunning mark from Swans star Heeney turned the match, cutting off an errant Dockers kick deep in defence before slotting the goal to start Sydney's momentum.

It was the first of eight consecutive goals for the finals bound Swans, Fremantle losing their skipper just before half time with his troublesome shoulder popping out, having initially sustained the injury against Western Bulldogs in round 12.

Michael Walters hurt his hamstring shortly after the break to join Fyfe on the sidelines, Sydney with their own concerns with Nick Blakey forced from the field after a crunching blow to the ribs.

Swans star Lance Franklin also faces a nervous wait for a crude elbow on Dockers defender Luke Ryan, likely to draw the attention of Match Review Officer Michael Christian.

Adam Cerra broke the run of Sydney goals early in the last but the game was safely in the Swans keeping courtesy of their five goal to nil third term, Heeney finishing with five majors in a superlative performance.

Midfield stars Josh Kennedy (34 disposals) and Luke Parker (32 disposals and 2 goals) alongside Heeney were the Swans most impactful players, while Cerra was Fremantle's best with 30 touches and 2 goals, fellow young midfielders Andrew Brayshaw (34) and Caleb Serong (26) also influential.

Dockers coach Longmuir said in his post-match media conference that Fyfe would likely require the season-ending surgery, while it would be a tough ask for Walters to return by season’s end.

“To lose your captain before halftime is not ideal,” Longmuir said.

“That shoulder looks like it's the same injury he’s had this year and been playing with.

“The likelihood is he will probably go into surgery I’d imagine now that he has had a re-injure of it, his season might be done."

The Dockers mentor also confirmed Walters season was in doubt.

“Sonny’s got a hammy, so we'll get it scanned…we're getting close to the end of the year now as well, so he's going to cut it fine to get back this year.”

The Dockers will return home and serve 14 days of quarantine either side of playing and training, their round 20 clash with Richmond to take place at Optus Stadium, while Sydney face Essendon on Friday night.
