What it means for the GIANTS: The loss of Stephen Coniglio last week was another massive blow for the GIANTS, who have dropped four of their past five games. They must beat the Pies to arrest their form slump or the season might be over.

What it means for Collingwood: After last week's stunning upset on the road against West Coast, the Magpies are back in the important second spot. They must repeat the feat on the GIANTS' home deck if they want to stay there.

The stat: Collingwood dominated and kicked 3.6 to 0.2 in last year's semi-final to overwhelm the GIANTS at the MCG. The visitors fought back and only lost by 10 points, but they were helped by the Pies' poor accuracy in front of goal.

The match-up: Adam Treloar v Daniel Lloyd

The star Magpie, ranked 22nd in the Official AFL Player Ratings, has averaged 33.6 possessions per game this season and while he's not always a reliable kick, his running power hurts opposition teams. Lloyd (374th) did a solid job on Dustin Martin for most of the game last week and has the tank to go with the former GIANT.

It’s a big week for: Toby Greene

Set for an extended stint as a midfielder with Callan Ward (knee), Josh Kelly (calf) and Coniglio (knee) missing, the gifted forward becomes even more important to the GIANTS. Greene found plenty of the footy and kicked two goals against Richmond last week and will need to produce big numbers against the Pies.

Big call: Harry Perryman will be given the task of limiting star Magpie Steele Sidebottom, and the tough youngster will keep the wingman under 20 possessions for just the second time this season.
