The GIANTS will be without key midfielders Tom Scully and Adam Treloar for their clash against Port Adelaide on Saturday.

Scully was subbed out during the third term of the GIANTS’ 32-point win over Essendon and is expected to miss the next 3-4 weeks with an AC joint injury.

Meanwhile Treloar will be sidelined for the next 1-2 weeks with groin soreness.

Fellow on-baller Stephen Coniglio is also in doubt after copping a head knock from Adam Cooney in the final term.

Coniglio didn’t train on Tuesday but is expected to re-join the playing group for the club's main session tomorrow.

Midfielder Jacob Townsend is also in doubt this week after suffering a concussion in the NEAFL.

GIANTS defender Matthew Buntine will miss the next fortnight as he continues to recover from two recent concussions.

Buntine has been in career best form in 2015 but has suffered concussion in his last two matches in round 16 (Gold Coast) and round 18 (Fremantle).

The 21-year old, who re-signed with the GIANTS last month, sat out the round 17 game against Geelong and also missed the round 19 win over Essendon at Spotless Stadium.

GIANTS Head of Athletic Performance David Joyce said the club would be taking a cautious approach to Buntine’s return to play schedule with the player’s welfare the paramount consideration. 

“With the advice of specialists we’ll be playing a long game with Matthew to make sure everything settles down and look to have him back playing football later in the season,” Joyce said. 

“Matthew underwent scans and the results were good with no acute distress suffered.

“At this stage we are looking at him returning for the Carlton game in round 22 but due to his recent history of concussion, we will be taking a conservative approach.”

In better news Zac Williams is expected to be available for selection this week after missing last week with hamstring soreness.

Dylan Shiel (knee), Shane Mumford (ankle), Tim Mohr (knee), Liam Sumner (foot) and Pat McKenna (hip) remain in the rehab group.

The GIANTS play Port Adelaide at Adelaide Oval on Saturday, August 15 from 4.35pm AEST.
