Trengove, Scully, Gawn, Howe, McDonald and Strauss seem the possible ins, while Dunn is an interesting case given he was probably on the verge of being dropped before he was rubbed out. Strauss sounds like he's a chance given that he gave good drive for Casey DB has pointed out our lack of foot skills out of defence, while someone (Jaded?) wrote that Bartram was out for four weeks.
I think Jetta, Evans, Warnock, Petterd, Newton, Jurrah and perhaps Bate (although not according to the MFC.com.au player review) seem most at risk. I would have thought Nicholson would get another game, but it's plausible he could miss out since similar players might be coming into the side.
It depends a bit on how many changes we want, and how many guys with 0-2 games we're prepared to play.
