Adelaide has four new injury concerns from Saturday night's NAB Cup win over Hawthorn in Tasmania.

Hayden Skipworth (calf), Robert Shirley (hip), John Hinge (foot) and Nathan Bock (back) all finished the game on the bench and may miss Friday night's semi-final against Melbourne at AAMI Stadium.

And defender Jason Torney, who did not make the final 24 for the Hawks clash, reported a quad strain after training on Friday and also is unlikely to be available.

These new injuries may force Adelaide to introduce more young players into the mix on Friday night.

Experienced Ben Hart, who travelled to Tasmania as an emergency, is expected to play his first game of the pre-season.

But with captain Mark Ricciuto (hamstring), Matthew Clarke (calf), Jason Porplyzia (quad) and Michael Doughty (knee) all still on the way back from injuries, the Crows may need to call up 2005 draftee Richard Douglas and ruckman/forward John Meesen for their first games at this level.

Nathan Bassett (shoulder), Scott Welsh (stress fracture in leg), Scott Stevens (shoulder) and Darren Pfeiffer (back) will not be available until later this month.
