IN-FORM Carlton will be without two of its best midfielders to face West Coast, while skipper Tom Jonas has been dropped among six Port Adelaide changes for Saturday night's top-of-the-table clash with Collingwood.

In other round 19 team news, Essendon's forgotten top 10 draft pick Nik Cox is in to play his first game of the season, while Brisbane is missing Zac Bailey (calf) to face Geelong and Adelaide will be without Rory Laird (shoulder) for its match against Melbourne.

Maurice Rioi jnr is out of Richmond's squad altogether.

But the Blues top the news with reigning Brownlow medallist Patrick Cripps (cork) and Adam Cerra (hamstring) both ruled out, adding to the already absent Harry McKay (knee) to face the Eagles.

Ken Hinkley has bolstered his team with a host of quality inclusions to face the Magpies, with Jason Horne-FrancisCharlie Dixon and Trent McKenzie all back from injury and Willie Rioli returning after missing the loss against Carlton for personal reasons.

All the changes mean there's no room for captain Jonas, who played just one match after an extended stint in the SANFL before being dropped again.

Collingwood has regained leading goalkicker Brody Mihocek and ruckman Darcy Cameron, with Ash Johnson one of the omissions. Oleg Markov has been dropped to the sub role.

Cox comes back into Essendon's team for the first time since round seven, 2022, for Friday night's critical clash with the Western Bulldogs.

Brad Scott has lost patience with forward Sam Weideman, dropping him, while counterpart Luke Beveridge has the services of Bailey Smith among four changes after he missed last week's loss to Sydney through illness.

There's good and bad news for the Lions trying to rebound from a loss to Melbourne, regaining Josh Dunkley after two weeks on the sidelines with a calf problem, but losing dynamic Bailey to the same injury.

Richmond has dropped Rioli from its squad to face Hawthorn after the small forward was subbed out of last week's game and refused to speak to the coaching staff while on the interchange bench.

The youngster is not even an emergency, with mid-season recruit Matthew Coulthard to make his debut as the sub.

The Hawks have recalled Seamus Mitchell and elevated Denver Grainger-Barras into their 22, with Lloyd Meek dropped again.

In Saturday's other game, Sydney has regained Chad Warner (calf) and Jake Lloyd (concussion) for the trip west to face Fremantle, which has Caleb Serong back, but lost four players to injury. Ethan Stanley, taken in the mid-season draft, will make his debut as the Dockers' sub.

Jack Higgins is back from a knee injury to bolster a struggling St Kilda team, while Jack Billings has also been included in its 26-man squad to face North Melbourne on Sunday.

Melbourne has named Brodie Grundy in its extended squad to face Adelaide but the former Pie is set to play in the VFL, with Adam Tomlinson confirmed as the replacement for Harrison Petty (ribs).

Laird is a huge loss for the Crows, who have also decided to rest first-year gun Max Michalanney.

Nick Haynes is in Greater Western Sydney's 26-man squad to face Gold Coast in Canberra.
