The Bombers coaching panel put their players through a very sharp 80-minute session at Colonial Stadium late this afternoon is preparation for this Friday night's clash with Port Adelaide. The Essendon players looked in good form in both competitive work and running drills. Damien Hardwick remains in doubt for this weekend's clash and spent the night running laps. David Hille, who suffered from a minor ankle injury in last weekend's VFL practice match against the Kangaroos, passed a fitness test before joining full training. He will line up against Frankston this Saturday afternoon in the VFL season opener at Windy Hill.
