Richmond have predictably welcomed back skipper Trent Cotchin for Sunday's key AFL clash with Brisbane but the Tigers have also tinkered with their ruck division by bringing in Noah Balta for the MCG encounter.
Cotchin returns from his third hamstring injury of the season, while the versatile Balta was preferred ahead of Mabior Chol as the back-up to Ivan Soldo, with Jack Ross also dropped.
Important defender Dylan Grimes has been named but remains under an injury cloud after badly rolling his ankle in last week's superb win over West Coast.
The ladder-leading Lions replaced the injured Allen Christensen with Cedric Cox for a game Richmond will likely need to win to cement a top-four spot.
Adelaide have made three unforced changes for their must-win clash with the Western Bulldogs in Sunday's early game at Mars Stadium in Ballarat.
Hugh Greenwood, Riley Knight and Alex Keath are in and Kyle Hartigan, Lachlan Murphy and Reilly O'Brien are all out.
The Dogs dropped Jackson Trengove and lost Tory Dickson to injury, but regained Tim English and Rhylee West.
The Crows must beat the eighth-placed Bulldogs and hope other results go their way to replace them in the eight.
Port Adelaide can also play finals depending on results, the Power adding Xavier Duursma, Scott Lycett, Trent McKenzie and Willem Drew for Sunday's encounter with Fremantle at Adelaide Oval.
Peter Ladhams, Zak Butters and Sam Powell-Pepper were dropped, with Tom Clurey ill.
After a week that saw coach Ross Lyon sacked, the Dockers made four changes, including Hugh Dixon, Scott Jones, Ryan Nyhuis and Bailey Banfield.
