Sydney defender Lewis Melican is staring down the barrel of an AFL suspension after collecting Toby Bedford high during a fiery clash against GWS on Sunday afternoon.

Bedford was running onto a loose ball in the forward 50, while Melican was approaching from the opposite direction.

The Giants tagger got to the ball first and tapped it on, but was met heavily by the swinging arm of Melican.

Melican’s arm appeared to connect with Bedford’s face and the Giant was on the ground for 30 seconds before finally getting to his feet.

He left the field in the hands of trainers with blood streaming down his face.

But Bedford passed his initial head injury assessment and was cleared to return to the field.

However, he was subbed out of the clash at half-time with an eye injury, according to the club.

The incident appears certain to result in a suspension for Melican.

It was the biggest flashpoint in what was an explosive first half. There were spotfires everywhere between the two fierce rivals.

But ultimately the fire and brimstone didn’t amount to much for the Giants, who let Sydney star Chad Warner run riot as the Swans snapped their losing streak with a 14-point win.

Beaten in their three previous games, the Swans rediscovered their form to lead at every change en route to a 12.15 (87) to 10.13 (73) victory in front of 39,260 fans at the SCG on Sunday.

Bedford was substituted out at half-time due to the swelling around his eye, replaced by Jake Stringer, who kicked three goals.

A suspension to Melican would be a massive blow to an injury-ravaged Swans outfit, with captain Callum Mills (foot), Tom Papley (heel) and Errol Gulden (ankle) among 11 players sidelined.

Swans midfielder Warner won the Brett Kirk medal as best afield for his 24-disposal, seven-clearance effort.

Winning the rematch of last year’s qualifying final, Sydney (3-5) have now beaten GWS in their past five meetings.

The Giants (4-4) extend their losing streak to three matches.

GWS midfielder Tom Green led the game with 34 disposals and six clearances, while teenager Josaia Delana - who arranged 80 tickets for family and friends to attend his debut - impressed with five tackles.

There were plenty of spotfires early as the Swans kicked five consecutive goals to set up a 21-point lead at quarter-time.

Giants defender Lachie Ash gave away a 50-metre penalty - and a goal - after a poorly timed attempt to punch the ball out of a marking James Rowbottom.

It took 20 minutes for the Giants to slot their first major, with Darcy Jones hitting the scoreboard before Aaron Cadman added another.

So dominant were the Swans in the first term that they took 20 inside-50 entries to eight.

GWS cut the deficit to six points in the second quarter, but Sydney held their nerve.
