Zadorov was defending along the wall on the right side of the Avalanche zone when a puck shot by Predators forward Ryan Johansen hit him. Zadorov remained down on the ice for a moment but was able to skate to the bench on his own and left the game at 4:33 of the second period.
Zadorov has three points (one goal, two assists) In 15 games this season. Selected by the Buffalo Sabres with the No. 16 pick in the 2013 NHL Draft, he has 65 points (19 goals, 46 assists) in 307 NHL games in seven seasons with the Sabres and Avalanche.
Center Nathan MacKinnon, who was held out of the third period Thursday after sustaining an upper-body injury at 17:53 of the second period, took a maintenance day Friday and is expected to be in the lineup when Colorado hosts the Columbus Blue Jackets at Pepsi Center on Saturday (9 p.m. ET; ALT, FS-O, NHL.TV).
The Avalanche are already without top-line forwards Mikko Rantanen and Gabriel Landeskog, each out with a lower-body injury.
