Cullen (knee) and Law (thigh) both required treatment after Saturday's goalless draw at Bolton Wanderers but the pair were able to take part in training at Apperley Bridge this Monday.
Despite the boost of having Cullen and Law available to him for the Fleetwood match though, McCall says he still hasn't ruled out making changes from the starting XI that took the field at the Macron Stadium.
Reflecting on the state of his squad ahead of the Fleetwood game, McCall said: "We are looking surprisingly well.
"Josh Cullen is a bit battered and bruised but he never wants to miss a game so he has trained this (Monday) morning. Nicky Law is the same.
"Other than the two who were out on Saturday - James Hanson and Tony McMahon - we have a clean bill of health.
"A few of them have some bumps and bruises but it certainly won't stop them being included in the squad.
"We have options once again within the squad to freshen things up should we wish.
"We will have a look back at the Bolton game, a few bits on Fleetwood and we will go with what we think is the best personnel and formation for the game."
