Watson was left out of the Wolves defeat because of a pulled stomach muscle will resume training tomorrow while Whelan, who limped out of the game on Sunday, looks to have shaken off a groin problem.
Tudgay meanwhile, who damaged his shoulder in the win against Rotherham United, should be able to play a part at the Valley, should he have no side-affects in the next few days.
No news so far on the progress of Franny Jeffers' calf problem but he is expected to be out for two weeks.
Still nothing coming out from the club about the signing of Reading's Sam Sodje although Brian Laws will be keen to get the deal done before the trip to south east London on Saturday.
Laws is also said to be in talks with a continental club about a midfielder after Manchester City's Ishmael Miller snubbed Wednesday to sign a loan deal at West Brom.
