Dumba signed a one-year, $3.9 million contract with Arizona in the offseason but has struggled out of the gate to produce with two goals, two assists, 25 SOG, 24 PIMs and a -9 plus/minus in 19 games and will be a healthy scratch Saturday. The 29-year-old will be replaced by Vladislav Kolyachonok, who is making his season debut.
