Star Celtic pair Reo Hatate and Liel Abada appear primed to feature in the squad to take on Rangers but Cameron Carter-Vickers appears a long shot for Saturday's showdown.
The returning duo – both sidelined with muscle complaints – have been absent for significant periods of the season but both were going at full pelt at Lennoxtown during the open access section of the session.
Abada was captured dribbling at maximum speed with the ball at his feet as he steps up his comeback. But Sky Sports had gloomier news regarding the USA international who was a Celtic no show in front of the cameras.
Carter-Vickers trudged down the tunnel at Dens Park with boss Brendan Rodgers retaining a degree of optimism over the potential of his star defender making a quick return.
