Huddersfield defender Lee Peltier is racing against the clock to be fit for the Galpharm Stadium clash.
The right-back was forced out of Saturday's 1-1 first-leg draw with a hamstring strain early in the second half and was replaced by Jack Hunt, who will retain his place if Peltier fails to make it.
Town manager Lee Clark must decide whether to stick with Antony Kay in central defence alongside skipper Peter Clarke, or recall Jamie McCombe, who made way on Saturday.
Clark has no other new injury or suspension problems, but goalkeeper Alex Smithies (knee), winger Anthony Pilkington (leg/ankle), midfielder Damien Johnson (knee) and defender Liam Ridehalgh (foot) are still sidelined.
The Terriers go into the second leg on the back of a club record 26-game unbeaten run after finishing the regular season in third place behind Brighton and Southampton.
Bournemouth manager Lee Bradbury has no fresh injury concerns ahead of the trip.
Michael Symes is back in contention having been sidelined for two months with an abductor strain, while both striker Danny Ings and midfielder Donal McDermott shook off knocks and came through the first leg unscathed.
It means Bradbury has virtually a fully-fit squad as he attempts to take Bournemouth one step closer to the League One play-off final at Old Trafford.
The tie is delicately poised at 1-1 after McDermott's long-range effort levelled the scores following Kevin Kilbane's header for Huddersfield.
The winners will play either Peterborough or MK Dons for a place in the Championship next season.
