MacArthur fails medical

OTTAWA (CP) — Clarke MacArthur’s future with the Ottawa Senators – and perhaps even as a pro hockey player – is once again in doubt after the veteran forward failed his medical on the first day of training camp. After missing much of the last two seasons due to concussion issues, MacArthur appeared to have turned a corner last spring when he returned in the final week of the regular season and played well during Ottawa’s run to the Eastern Conference final. But questions about his future lingered as he admitted to dealing with some discomfort in his neck.
