Matthew Rose and Clarke Carlisle are the only players absent from the squad after a good week from the QPR medical staff.
Marc Bircham, Tony Thorpe, Terrell Forbes and Wes Daly have all returned to full training this week leaving Holloway with some truely difficult selection problems ahead of the Kenilworth Road battle.
Thopre and Bircham returned to training on Thursday morning while Forbes and Daly enjoyed a 90-minute run-out for the reserves on Tuesday at Aldershot.
Bircham, Rowlands, Daly and Bean all have eyes on a midfield birth while Thope would love a striker's role alongside the inform Paul Furlong.
If Holloway chooses his preferred partnership of Bircham and Palmer then he'll have an abundance of talent to choose from at right back. Richard Edghill, Martin Rowlands and Forbes all challenging for the spot.
It gives Holloway an interesting headache ahead of the game at Luton.
