In an interview with website Collider, when asked if the two characters will making a follow-up appearance, Rhett said: "I think we can say. Yeah, they'll be in the sequel."
Paul added: "I can't say how much they are ... they'll make at least an appearance."
Reynolds will be reprising his role as Wade Wilson and his alter ego Deadpool - a mercenary who has regenerative powers due to an experimental treatment to cure his cancer - and X-Men member Cable will be joining as a new character.
Reynolds, 40, hopes to continue in the franchise - which he kick-started due to his love of the Marvel comic book character - for as long as possible.
He previously said: "I would love to play 'Deadpool' for as long as they would let me play 'Deadpool'. We have outlines and stories for a number of different films."
The sequel will be directed by David Leitch.
