OTTAWA, Ontario -- Ottawa Senators forward Clarke MacArthur has failed his training camp physical examination.

The 32-year-old MacArthur has 133 goals and 171 assists 552 career regular-season games with Buffalo, Toronto and Ottawa. In 2014, he signed a contract extension through the 2019-20 season with an average annual value of 4.65 million.
