The Toronto Maple Leafs announced Wednesday that defenceman Mike Van Ryn has elected not to play in the 2010-11 season.
Van Ryn, 31, has been rehabilitating his left knee after undergoing a knee re-alignment last October.
He did not appear in a game last season due to the injury. The native of London, Ontario joined the Leafs in a trade with the Florida Panthers in September of 2008.
Van Ryn is slated to become an unrestricted free agent on Thursday.
