Mukhamadullin (lower body) was placed on the injured non-roster list Monday, Sheng Peng of San Jose Hockey Now reports.
Mukhamadullin has been dealing with a lower-body injury since before the start of training camp, and he didn't return to full health during preseason action. It's not yet clear when he'll be ready to return, but the 22-year-old could head to the minors once he's deemed healthy.
