Adelaide’s Josh Jenkins has lost his fight to play in Saturday night’s top-of-the-table AFL clash against Port Adelaide.

The second-placed Crows have ruled out the centre half-forward with the bruised ribs he suffered against Hawthorn last week and replaced him with young defender Jake Lever.

The unbeaten Power also made just one change, replacing injured defender Jack Hombsch (knee) with Hamish Hartlett after he missed last week’s thrashing of Fremantle with an illness.
