SELECTION dilemmas loom for both the Western Bulldogs and Sydney Swans ahead of Saturday's Grand Final, with several players facing a race against time to be fit.

At the top of the Bulldogs' list is ruckman Jordan Roughead, who was forced off early in the second quarter of Saturday's stirring six-point win over Greater Western Sydney with hyphema, or bleeding, in his right eye.

The 25-year-old was struck flush in the face from a ball that was kicked by Giant Rory Lobb and did not return to the field thereafter.

Ophthalmologist Dr Andrew Atkins examined Roughead's eye on Sunday.

"He's got blurry vision. We just have to wait and see how he goes," Dr Atkins told Channel Seven on Sunday night.

"Hopefully it'll clear up but it's too early to make a call on how that's going to progress during the week." 

Ruckmen Tom Campbell and Will Minson took part in Footscray's VFL Grand Final win over Casey on Sunday and will come into consideration should Roughead not recover in time.

Midfielder Lin Jong made a successful comeback in the VFL decider from surgery to repair a broken right collarbone – 17 days after suffering the injury in the elimination final against West Coast.

Dog's trick pays off with VFL premiership

Bulldogs defender Fletcher Roberts was brought into the preliminary final side to replace Matt Suckling, who was ruled out against the Giants due to Achilles soreness.

The Swans, meanwhile, are clinging to the hope Aliir Aliir will be available for the premiership decider at the MCG after scans cleared the defender of serious knee damage.

Aliir strained the medial ligament in his right knee late in the first quarter of Friday night's 37-point preliminary final win over Geelong.

The 22-year-old succumbed to the game-ending injury in a marking contest against Cat Lincoln McCarthy.

Aliir hobbled off the ground in the hands of trainers and had his medial ligament strapped, before performing straight-line run-throughs along the boundary.

The 193cm backman was limited in his lateral movement and spent the rest of the game with ice strapped around his knee.

Aliir clear of major damage, but doubt remains

Should Aliir not be available, retiring Swans veteran defender Ted Richards could enter the selection frame in what would be a fairytale finish to his 15-year, 261-game career.

Richards has played eight games for the Swans this season, including just two matches since round nine.

The Swans face other selection conundrums, with co-captain Jarrad McVeigh and NAB AFL Rising Star winner Callum Mills pushing to return from their respective injuries.

McVeigh strained his left calf in the semi-final against Adelaide, while Mills suffered a low-grade hamstring strain in the qualifying final loss to the Giants the week prior.

The pair will have to get through training this week before a decision is made on their availability.

Swans midfielder Luke Parker picked up a sore left knee in a marking contest early in the third quarter and had his medial ligament strapped, but the 23-year-old has declared himself a certain starter.

Fellow ball-winner Josh Kennedy began the second half with protective strapping around his right knee, but also got through the match against the Cats with no major concerns.

The Swans confirmed the All Australian duo had scans over the weekend but were cleared of knee damage. 

Parker, Kennedy and superstar forward Lance Franklin – arguably the Swans' most important trio – ended the big win over the Cats on the bench, as the club's attention quickly shifted to the Grand Final. 

In other injury concerns at the weekend:

- Greater Western Sydney co-captain Callan Ward was left heavily concussed after receiving an accidental knee to the side of his head from Bulldog Zaine Cordy in a second-quarter marking contest. Play was halted for several minutes as the Giants' medicos and trainers attended to Ward, before slowly assisting the defender off the ground. Ward watched the rest of the game from the interchange area.

- Geelong defender Harry Taylor suffered a right hand injury in the second quarter against the Swans and was assessed in the rooms at half-time. The 30-year-old battled through the second half with a strapped hand/pinky finger and featured in the forward line.
