The Lions issued a warning that the best players must be played in the warm up matches
Lions assistant coach Andrew Goodman's expecting to face a strong Western Force side on Saturday, despite an ongoing row over player availability.
The Lions have warned hosts Australia they must field the Wallabies' best players in the warm-up matches, before next month's Test series.
Goodman says it'll be a tough match in Perth this weekend.
Meanwhile, Ireland attack coach Mike Prendergast says having three players battling it out for the Ireland 10 jersey can only be a good thing.
Jack Crowley, Suncroft's Sam Prendergast and Ciaran Frawley are all in contention to start next week's match against Georgia in Tbilisi.
