Flint said Hunt had responded well to his training.
"Mark's weight is 100 per cent on track. I'm very pleased; it should be a smooth run into weigh-in," Flint said. "My primary concern is maintaining his strength through a fortified diet and cycling his food intake to ensure maximum energy uptake."
Hunt's striking coach, Lolo Heimuli flew into Mexico City yesterday and had quickly integrated a plan for the well-rounded Werdum.
"With a veteran like Mark, it's just getting the strategy right. Small details count in making timing work in a split second, so we'll be working on this - you don't teach the old dog new tricks but you can open the door for him to use the ones he has."
Wedrum (18-5-1) has won his past four bouts in the UFC, including a win against Roy Nelson who Hunt beat by knockout in September.
