Buffalo Sabres defenseman Nikita Zadorov is in trouble once again.

Zadorov has been scratched for Sunday's game against the Nashville Predators for what Buffalo Sabres head coach Ted Nolan described as team reasons.

"Sometimes you're mature in certain things. Sometimes you're not," Nolan told reporters at Sunday's practice. "Unfortunately, we'll have to deal with him."

Zadorov was also suspended after failing to report on time following the All-Star break.

"We had a number of discussions, and then another thing happened this morning. We'll just talk to him again."

The 19-year-old has 13 points in 42 games.
