The Blackhawks traded veteran center Artem Anisimov to the Senators in exchange for forward Zack Smith on Tuesday.
Smith, 31, had nine goals and 28 points last season in 70 games. He has two seasons left on his contract worth $3,250,000 with a 10-team no-trade clause.
Anisimov scored at least 15 goals and 31 points in four seasons with the Blackhawks after he was acquired in June 2015 when the Blackhawks sent Brandon Saad to the Blue Jackets. Anisimov eclipsed the 20-goal and 40-point marks in each of his first two seasons with the Blackhawks while playing with wingers Artemi Panarin and Patrick Kane, but saw his offensive production dip once Panarin was dealt to Columbus.
