Brazeau (lower body) was assigned to AHL Wilkes-Barre/Scranton on a conditioning loan Wednesday.
Brazeau has been sidelined for the start of the regular season due to his lower-body injury, but Wednesday's move signals that he's trending in the right direction in his recovery process. It's not yet clear when he'll be in the mix to appear in games at the NHL level, but the 28-year-old will likely have a chance to carve out a regular role for Pittsburgh once he's fully healthy.
