Plymouth could welcome back Conor Grant for the visit of Charlton.
The midfielder is closing in on a return after two weeks out with a groin injury.
Defender Sam Woods is also close to making a full recovery following a hamstring strain.
George Cooper remains the only long-term absentee.
Charlton duo Conor Washington and Chuks Aneke are due to return to training.
Washington has been missing since the 2-2 draw at AFC Wimbledon last month due to a hamstring problem, while fellow forward Aneke has not featured since the Good Friday victory over Doncaster with a groin injury.
The pair may not be available to face Argyle but should be involved soon.
Ian Maatsen missed out at the weekend with a hip injury and will be assessed.
