Star midfielder Tom Liberatore has been controlled out of the Western Bulldogs' AFL end last against Fremantle.

In a significant blow for the Bulldogs, their leeway machine won't abandon 

Optus Stadium on Saturday night in the wake of experiencing a hamstring injury. 

Liberatore hurt himself at preparing last week and may be thought of in the event that the Dogs upset the Dockers in Perth and win through to a semi-last.

Liberato has the fifth most clearances in the association this season.

The 30-year-old was one of the Bulldogs' best when they lost to Fremantle by 17 at Marvel Stadium a month prior.

The Dockers were dealt a blow Tuesday when Whiz chief Nat Fife was ruled out of his own hamstring problem.

It is the opposite leg of a hamstring injury that sidelined Fyfe for three games before his return to success at GWS in cycle 23.
