Do Trainers Need to be Listed on Team Rosters? Is this new?

Is this a NEW requirement??? Must Referees id them before the
game, along with coaches & players. We are referring to the Home team!!!

Bill, this is not new!

Referred to Rule 3, Section 1, Art. 3.  All bench personal (which includes the Trainer) are included on roster and may be added after the start of play!
