Labadie is available again after a two-match suspension and highly-rated youngster Dale Jennings may also come back into contention.
The rookie striker has been sidelined with a groin injury but stepped up his training this week and will hope to play some part against the Addicks.
However, Alan Mahon, Ryan Fraughan and Marlon Broomes could all remain sidelined through injury.
Parry, meanwhile, has said he will weigh up whether to recall Labadie to his starting line-up after Rovers performed impressively during Tuesday`s 1-1 draw at Exeter.
"The lads did so well on Tuesday and it`s a nice problem to have," said Parry.
