THE SYDNEY Swans, Hawthorn and the Western Bulldogs will this week weigh up suitable candidates to replace their injured personnel ahead of their crunch semi-finals.

Swans defender Callum Mills injured his right hamstring in the second quarter of the qualifying final loss to GWS on Saturday, while ruckman Kurt Tippett suffered a non-displaced hairline fracture in his jaw in the first term. 

The key Swans have been ruled out of Saturday night's semi-final against Adelaide at the SCG.

Week two finals fixture: Hawks-Dogs kick off semis

Mills, who took out the NAB AFL Rising Star award last week, pulled up lame and immediately grabbed his upper leg as he attempted to compete in a marking contest at half-back. 

The 19-year-old slammed his fist into the ground in frustration as he received treatment at the interchange area, and sat out the rest of the match with ice strapped around his injured leg.

Tippett, meanwhile, was forced off the ground after his head became caught between Giants Callan Ward and Shane Mumford in a collision at a ruck contest.

The 29-year-old passed a concussion assessment and returned to the field, only to be crunched in a tackle from Mumford, but he battled through the rest of the match.

Swans midfielder Josh Kennedy was also left dazed in the first quarter after being collected high by Giant Steve Johnson in an incident that will come under Match Review Panel scrutiny.

Like Tippett, Kennedy came off the ground and was cleared to return in the second term after passing a concussion test.

Hawthorn youngster Ryan Burton is racing the clock to be fit for Friday night's semi-final against the Western Bulldogs at the MCG.

Burton suffered a knock to his right calf against Geelong on Friday night and did not return after leaving the ground in the second term.

The 19-year-old emerged from the rooms early in the third quarter with his calf heavily strapped, but played no further part.

Hawks coach Alastair Clarkson said Burton had suffered "a pretty savage corkie" and added the club would "wait and see how that settles down over the course of the week".

Hawthorn defender Taylor Duryea picked up a left thumb injury late in the second quarter after landing on his hand in a marking contest. 

The 25-year-old received medical attention but returned to see out the game.

Tall forward James Sicily, who was a late withdrawal against Geelong through illness, looks set to be available.

Western Bulldogs midfielder Lin Jong was reduced to tears on the interchange bench after breaking his collarbone midway through the second quarter of the elimination final win over West Coast on Thursday night. 

The 23-year-old was pinned in a heavy, but legal, tackle from Eagles defender Jeremy McGovern and immediately came off the ground cradling his right arm. 

Jong posted a message on social media late on Friday afternoon to say "surgery went well" and thanked fans for their well wishes.

The 188cm ball-winner is out of contract and may have played his last game for the Bulldogs, having received interest from Gold Coast and Collingwood.

Forward Tory Dickson sent a scare through the Bulldogs' camp in the closing minutes of the sudden-death final after reaching for his right hamstring while taking an uncontested mark at half-back.

The 28-year-old jogged off the ground and received a rub down from the club's physios.

Bulldogs coach Luke Beveridge said Dickson was likely to have just suffered cramp, although he could not give a definitive answer without consulting the medicos.

The Bulldogs welcomed back stand-in skipper Easton Wood (ankle), Tom Liberatore (ankle), Jackson Macrae (hamstring) and Jordan Roughead (calf) from their respective injuries last week.

Geelong tall Rhys Stanley received medical attention for a left adductor issue during the third quarter against Hawthorn, but returned to the field with a heavily strapped upper leg.

Cats midfielder Sam Menegola also needed treatment in the third term on his right calf/shin after receiving an accidental boot from teammate Harry Taylor as the defender tried to kick the ball. 

Menegola returned after a spell on the bench and got through the tense final quarter with no major concern.

West Coast ruckman Scott Lycett requires post-season surgery on his left knee.

The 23-year-old carried a posterior cruciate ligament issue from around the mid-season bye and was carefully managed in the second half of the season.

Lycett received a knee knock early in the game against the Bulldogs but got through despite being somewhat restricted in his movement.

North Melbourne defender Aaron Mullett was taken to hospital for further assessment after being involved in a heavy collision in a final-quarter marking contest with teammate Jack Ziebell and Crow Eddie Betts. 

Mullett was slow to get to his feet and was monitored for any potential rib or internal damage.
