Coach Dave Cameron said that MacArthur is dealing with the flu and will not play Saturday against the Oilers, Bruce Garrioch of the Ottawa Sun reports.MacArthur also missed a game in December due to illness, but he's otherwise been a picture of health for the Senators, suiting up in 52 games. His absence Saturday will deprive the team of a top-six forward, with Mike Hoffman more than likely sliding up to the Mika Zibanejad-Bobby Ryan line to cover for him.
