Cloke had merely suffered a dislocated finger and returned to the rooms to have it put back in.
Collingwood midfielder Dane Swan, who is due to play his 200th game on Saturday, said Cloke had reassured him the injury was not significant.
"From all reports he's fine to go," Swan said. "They popped his finger back in and I just saw him then and he said 'he's fine', so he is fine."
Cloke was one of the Magpies shining lights in the defeat against Hawthorn, kicking five goals. He has now kicked nine goals in the first three rounds.
With a long injury list including Darren Jolly, Nick Maxwell, Dayne Beams and Ben Johnson on the sidelines through injury, the club could not afford to be without Cloke.
