Arizona Coyotes winger Tobias Rieder will not attend training camp if a contract extension with the club has not been reached, according to Dhiren Mahiban.

Mahiban reports that there would be visa-related challenges for Rieder, a native of Germany, to attend camp without a contract in hand.

The 23-year-old is a restricted free agent and must sign by Dec. 1 in order to play in the coming season.

Rieder's agent, Darren Ferris, has mentioned the possibility that his client could sign in the KHL if a deal cannot be reached with Arizona.

His camp is believed to be seeking a two-year deal worth about $2.75 million per season. He scored 14 goals and 23 assists with the Coyotes last year.

Participating with Team Europe at the upcoming World Cup, Rieder will not decide on the KHL until the conclusion of the tournament.
