Star Hawthorn duo Isaac Smith and Luke Breust have withdrawn from Friday night's AFLX tournament, as reported by AFL.com.au.

They join Hawks teammate Chad Wingard in pulling out of the one-night event at Marvel Stadium, leaving Jack Riewoldt's Team Rampage in need of two replacements.

It is currently unknown who will take their place and if they will come from Hawthorn.

Smith and Breust are expected to be available for the Hawks' practice match against Carlton on Thursday at IKON Park, however, Wingard will miss the hit out with a calf injury.
