Amir was taken from the field on a motorised stretcher during last week's first Commonwealth Bank Test after digging his knee into the Gabba turf.
The left-arm quick appeared in agony but made a surprise return a short time later and continued to bowl.
Amir had his knee strapped before a light bowling session in the nets at the MCG on Thursday.
Pakistan batting coach Grant Flower said,
“
There's quite a bit of bruising on his thigh, He's feeling a bit stiff but he's alright. The guys are fit enough to go through and I think our attack would probably be the same.
