But the big news comes from the Demons, who have done away with their two-ruck system, dropping off-season recruit Grundy for the first time in 2023 and naming Jacob van Rooyen to face the Lions at the MCG.
Brisbane has recalled Jarrod Berry (hamstring) and Lincoln McCarthy (suspension), with youngster Deven Robertson missing out.
Captain Tom Jonas will play his first game for Port since round 10, in for the injured Trent McKenzie, but Ken Hinkley will also be without Charlie Dixon (soreness) and Jason Horne-Francis (back) among seven changes to face the Blues.
Ruckman Scott Lycett is back, while wingman Xavier Duursma also returns following two games in the SANFL after overcoming a knee injury.
Tom De Koning is back for the Blues after missing a month with a knee injury.
Collingwood has three big inclusions to face Fremantle on Saturday, with Dan McStay, Steele Sidebottom and Brayden Maynard all back from injury, while Mitchell was listed as 'rested' when teams were announced on Thursday night, however the club later said the prolific midfielder would start as the sub.
The Dockers have made four changes for the must-win match, with Joel Hamling playing his first game since round two, 2022.
Gold Coast interim coach Steven King will be without running defender Lachie Weller (knee soreness) for his first match in charge against St Kilda, while Elijah Hollands has been named for the first time since round four.
Josh Battle comes back from concussion and Brad Hill from a knee injury for the Saints.
In Saturday night's mouth-watering contest at GMHBA Stadium, Geelong has the services of star forward Cameron again after two weeks on the sidelines, while Essendon will be without injured Dylan Shiel.
Adelaide has regained full-back Jordon Butts (concussion) to face Greater Western Sydney, also naming Shane McAdam, while speedy forward Brent Daniels is back for the Giants from a hamstring injury.
West Coast has strengthened its team to host Richmond on Sunday, selecting Luke Shuey and Shannon Hurn after both veterans were rested for the long trip to Brisbane last week.
Sam Petrevski-Seton has also been named on an extended bench.
The Tigers have recalled Ivan Soldo to replace suspended skipper Toby Nankervis, while young ruck Samson Ryan is in the 26-man squad.
In Sunday's other match at Marvel Stadium, James Sicily is straight back in after his three-match ban to lead Hawthorn against North Melbourne, with the Hawks also adding Luke Breust (throat) to the extended squad.
The Kangaroos have made at least three changes as they seek to snap a 14-game losing streak, but regain first-year sensation George Wardlaw after he missed last week through illness.
