Neither fighter has been in the ring since their first bout 10 months ago and Hughes said it would be “naive” to think that Johnson will follow exactly the same tactical plan as before.
She said: “I’ve been working for the last 10 months and improving, so we’re both probably going to bring something new to the table, and I’ll prepare for everything.
“Her style will probably be pretty much the same, the way she walks forward with her hand up high. She’ll probably be busier but I’ve got to be prepared in case she does bring something completely different.
“We’ll have all different sparring partners in and I’ll be practising everything just in case.”
If Hughes is successful, she wants to press ahead with future fights against rival champions Dina Thorslund (WBC and WBO) and Shurretta Metcalf (IBF)
“I’m not looking too far ahead because I’ve got to win this one but ever since I won that world title, the goal after that was to become unified (champion) and start collecting the other belts,” she added.
“Unfortunately it never materialised but hopefully I get back my world title and we can look into that.”
