North Melbourne has opted for an unchanged line up for Good Friday.

Despite coming home from Cairns empty handed, the match committee is backing in the same 22 players to get the job done against St Kilda this week.

However, the Roos may make a change as indicated by Brad Scott yesterday, when he spoke to the media during his weekly interview.

"We'll certainly pick some extra talls in our squad and then make a decision late," Scott said.

The "talls" consist Majak Daw, last week's travelling emergency, and Ben McKay.

According to Scott, Daw is "fresh and ready to play" and McKay had "probably his best game in defence" last week against Coburg in the VFL.

The pair could be used in combination with Robbie Tarrant, Scott Thompson and Ed Vickers-Willis to match up on the likes of the Saints' tall forwards in Tim Membrey, Josh Bruce and Paddy McCartin.

At the other end of the ground, Mason Wood could be brought in to help bolster North's goal-kicking ability. After missing a chunk of the pre-season with a thumb injury, the young forward is looking for his first game of the season.
