THE INJURY-HIT Western Bulldogs will on Monday find out the results of scans to injured midfielders Tom Liberatore and Jack Macrae, and whether the pair will be available come finals.

Liberatore limped off the ground midway through the second quarter against Geelong with a left ankle syndesmosis injury after his leg was caught under a tackle by Cats speedster Steven Motlop.

The 24-year-old had ice applied to the injury following the club doctor's initial assessment and required a protective moon boot and crutches for the rest of the night.

The ankle syndesmosis is the joint between the tibia and fibula bones.

Macrae, meanwhile, reached for his right hamstring straight after being brought to ground in a tackle by Motlop.

The 21-year-old was assessed late in the third term and performed a few tests during the three-quarter time break, but did not reappear.

The Bulldogs made five forced changes for last Friday night's clash, with Matthew Boyd (Achilles), Dale Morris (hamstring), Matt Suckling (Achilles), Mitch Wallis (broken leg) and Jack Redpath (knee reconstruction) all casualties in the loss to St Kilda in round 18.

GWS tall forward Rory Lobb grimaced in pain after landing awkwardly and having his left ankle trampled on by Tiger Ty Vickery in a marking contest late in the third term.

Lobb struggled to put any weight on his leg, later emerging from the rooms wearing a moon boot and with ice strapped around his knee.

Speaking post-match, Giants coach Leon Cameron confirmed Lobb had suffered an ankle injury, with scans needed to determine the full extent.

In his comeback from a right hip complaint, Kangaroos forward Jarrad Waite went into the rooms at quarter-time after aggravating the same injury.

The 33-year-old reappeared halfway through the second term but was clearly restricted in his movement across the ground.

Waite came off in obvious discomfort after converting a set shot in the third term and failed to appear thereafter, featuring in just five minutes of the second half.

The Kangaroos' goalkicker has missed five of the last six games due to the lingering hip complaint.

Collingwood forward Darcy Moore suffered a hamstring setback midway through the second term and was taken into the rooms for further treatment.

Moore performed a few run-throughs along the boundary at the start of the third quarter, but the Magpies opted not to risk the goalkicker for the rest of the game.

Adelaide also took a no-risk approach with ruckman Sam Jacobs, who walked off gingerly in the early stages of the second quarter against Essendon after rolling his left ankle in a marking contest.

The 28-year-old was assessed and had his ankle re-strapped, before hopping on an exercise bike at the interchange area.

A few minutes later, the medical staff had another look at Jacobs' injury and decided to wrap an ice pack around his lower leg.

Speaking post-match, Crows coach Don Pyke said the early prognosis was "a low-grade strain", adding the big man would be given every chance to prove his fitness for Saturday night's home clash to the Brisbane Lions.

In other injury concerns at the weekend:

- Port Adelaide's Hamish Hartlett was a late withdrawal against the Brisbane Lions with a calf injury he picked up in the warm-up, and was replaced in the side by Jimmy Toumpas.

- Carlton defender Jacob Weitering hobbled off the ground in the final term with a corked right shin he suffered in a marking contest. He had the injury strapped but was in considerable pain.

- Demon James Harmes was left dazed after taking a courageous mark and colliding into Sun Kade Kolodjashnij in the centre of the ground during the third quarter. Harmes came off for a brief spell and returned to the field.

- Kangaroo Brad McKenzie limped off in the final term after receiving a knee to the right shin from Saint Luke Dunstan, but managed to see out the match.

- Hawks youngster Kaiden Brand underwent the routine concussion testing in the rooms after being involved in a head clash with Blue Dennis Armfield in the first term. Brand returned to the field later in the first quarter and played out the game.

- Giant Steve Johnson was sporting a heavily bandaged head in the second half against Richmond after receiving a cut above his right eyebrow from Oleg Markov's attempt to spoil in a marking contest.

- Hawk Ben McEvoy had his head bandaged in the final minutes of the match against Carlton following an accidental head clash with Blue Andrew Phillips.
