Australia captain Michael Clarke is optimistic key seamer Ryan Harris will be fit for the crucial third Ashes Test in Perth despite his sore knee.
Harris had only a light bowl at nets on Thursday, but did eventually work up to full pace.
If he were unavailable, Australia might have to look outside their 12-man squad to the two pace bowlers on standby after all-rounder James Faulkner took a painful blow to his hand in the nets on the even of a match in which Australia are hoping to wrap up the Ashes 3-0.
Doug Bollinger and Nathan Coulter-Nile are Australia's two other options, but Clarke said: "I hope everyone will come up.
"There is the obvious one, in 'Rhino' bowled today, so we are going to wait and see how he pulls up.
"But I am confident he will be fine."
