Both players have colds, and Sam Sodje may miss out with a head injury suffered in training.
Boss Pardew recieved the backing of chairman Richard Murray in the week, and knows that a draw or defeat will practically end the Addicks chances of reaching the play-offs, and with that in mind, he will start with an attacking 4-4-2 formation.
Leroy Lita should start upfront with Chris Iwelumo, and Luke Varney may feature on the wing.
Madjid Bougherra could also replace Sodje in the heart of the defence.
Possible side for Plymouth: Weaver, Halford, Bougherra, McCarthy, Thatcher, Varney, Zheng, Holland(c), Thomas, Lita, Iwelumo
Subs: Elliot, Sodje, Semedo, Ambrose, Cook
