Lipinski suffered a calf injury in the loss to Geelong that also featured injuries to his teammates Jeremy Howe and Harry Perryman.
Howe fractured his left forearm against the Cats with a timeline on his return yet unknown, while Perryman suffered a hamstring strain and will miss at least three matches.
Star Magpie Jordan De Goey is in doubt for Sunday's away game against West Coast because of a glute injury.
Four Magpies - captain Darcy Moore (hamstring), Jamie Elliott (knee), Reef McInnes (knee) and Oscar Steene (knee) - are out for the rest of the season while defender Brayden Maynard (knee) is at least two weeks away from returning.
Meanwhile, Melbourne backman Daniel Turner is in the selection frame for Saturday's clash against ladder-leaders Fremantle.
Turner has been sidelined since July 18 because of a rib injury and will face a fitness test later this week.
The Demons also expect goalsneak Latrelle Pickett (concussion) to be available while Kade Chandler could also make his comeback from a broken hand suffered a fortnight ago.
Carlton backman Jack Silvagni remains a chance to play against St Kilda in Sunday's finals-shaping fixture between the 10th-placed Blues and 11th-placed Saints.
Silvagni dislocated his right shoulder in the loss to Sydney last weekend.
"We will continue to closely monitor Jack throughout the week to assess the level of function within his shoulder and ultimately how he's feeling," Saints football manager Lenny Hayes said.
Blues key defender Jacob Weitering also could play his first game since a calf injury on May 29, if he gets through training this week.
Second-placed Sydney expect on-baller James Rowbottom to miss three to four weeks because of a broken hand, while also losing Will Edwards (broken ankle) for the year.
Adelaide defender James Borlase has been cleared of a hamstring strain after reporting tightness during his side's win against Essendon on Sunday.
Gold Coast defender Sam Collins could return from a rib injury for his club's clash against GWS on Sunday in Canberra.
Giants skipper Toby Greene is pressing to return from a thigh injury but teammate Darcy Jones won't play this season as he continues his recovery from a knee reconstruction late last year.
Jones is the eighth GWS player out for the season because of injury.
Richmond have also lost a duo for the remainder of the year with Sam Cummings' first AFL season cut short by an ankle injury and Rhyan Mansell out because of a foot injury.
