The incident occurred during Game 2 of the first-round series between the Predators and Sharks. Radulov was ejected after the play at 4:44 of the second period.
Radulov will miss Game 3 on Monday and is eligible to return for Game 4 on Wednesday in San Jose.
The 20-year-old rookie was off to a hot start in the best-of-seven series, which is tied at one game apiece. Radulov had three goals and an assist in slightly more than four periods.
Also Saturday, the NHL rescinded two game misconducts called on Predators forward Scott Hartnell in the final minute of Game 2.
