The 27-year-old, who has joined the Wildcats on a two-year contract from Parramatta, was sent off for punching just 18 minutes into his first appearance for the club in their Boxing Day defeat at Leeds.
Anything more than a one-match ban would have forced him to sit out Wakefield's opening Super League game against Bradford on February 3, but he was charged with a minor grade A offence and was able to submit an early guilty plea to avoid any suspension.
The case was held up while the Rugby Football League obtained details of his NRL career to establish his right to enter into plea bargaining.
Poore, who has now lost the right to submit an early guilty plea for the next 12 months, is currently with Wakefield at their training camp in Portugal and has been named in coach Richard Agar's squad for Sunday's home friendly against Featherstone.
Fellow front-rower Brad Singleton, who has joined the Wildcats on loan from Leeds, is set to make his debut in that match.
