GWS have confirmed that co-captain Jake Kelly will be sidelined for Round 19's trip to Melbourne to face Carlton, after the 27-year-old was placed in concussion protocols.

Kelly suffered a concussion in the last term of the Giants' loss to Brisbane in Round 18 and subsequently failed a concussion test post-game. The midfielder has played every game for the Giants so far this season, but will now be unavailable for twelve days per AFL guidelines.

The Giants have also confirmed that Connor Idun will be sidelined for four-six weeks after breaking his foot. The young defender made his return to the senior side in Round 18 after missing the previous week through the league's health and safety protocols, with scans now leaving his season potentially over.

GWS Head of Medical James Rahme spoke to club media, confirming that while the 21-year-old did suffer a break, he won't need surgery.

“It’s really disappointing for Connor who’s had a great season,” Rahme said.

“He reported soreness following the game and upon investigation, scans revealed a break in his right foot.

“He won’t require surgery but will be in a moon boot for the next few weeks and we anticipate he’ll be sidelined for at least a month.”

Elsewhere at the club, both Lachie Whitfield (hip) and Adam Kennedy (concussion) are chances to return this week, both facing tests on their respective ailments before being given the all clear.

Midfielder Harry Perryman is still at least one week away as he continues to recover from breaking four ribs during Round 13's win over North Melbourne.
