The Kings’ newly signed defenseman Larry Robinson, may sue the Montreal Canadiens for a retirement bonus he said was promised before he signed as a free agent.

Robinson, 38, and his agent Don Cape said Canadien General Manager Serge Savard promised one year of full salary after his retirement but later placed on it a condition that he finish his NHL career in Montreal.

Robinson turned down a one-year, $1-million offer, which included the bonus, from the Canadiens last month to accept the Kings’ contract for two years plus an option year worth $1.5 million.
