Star Giants duo Stephen Coniglio and Lachie Whitfield are racing the clock to be fit for next week's clash against St Kilda.

Coniglio dislocated his finger during Saturday night's win over Sydney and had to wear a glove in the second half, but still starred with four goals and 24 disposals.

Whitfield suffered a badly corked thigh and sat at full forward for the majority of the game thereafter.

Additionally, co-captain Phil Davis was a late withdrawal against the Swans after failing to overcome an ankle injury.

Giants coach Leon Cameron said Coniglio and Whitfield would come under fitness tests during the week.

"Coniglio was really brave to play on, we don't know how bad it is," he told reporters post-match.

"He's hard and he's tough and I thought he played his role really well.

"For him to hit the scoreboard and play good midfield time speaks volumes about who he is.

"If it's right (for next week) he'll push on but if it's not we'll see where that leads.

"For his build, Lachie is as hard as anyone at our footy club, and he cracks in probably too much at times, and he's really sore.

"But he was the first one to put his hand up to play on and he was hampered, but it allowed us to keep rotating our players.

"We'll give him every chance (to play next week), like we did with Davis (this week), but we'll assess that during the week."

GWS meet St Kilda next Saturday afternoon at Manuka Oval.
