Neil Harris put Kenny Jackett's men ahead in the first half, turning in a Dave Martin cross but a goal from Franco Georgescu twelve minutes from time levelled the scores.
The Lions fielded two different sides in each half, allowing manager Jackett to cast his eye over his troops with debuts for new signings David Forde, Ashley Grimes and Jimmy Abdou as well as a run out for trialist Charlie Daniels.
