MacArthur diagnosed with concussion after hit by Senators hopeful Sieloff
Clarke MacArthur is dealing with another head injury, and this one occurred in a controversial manner.
Senators general manager Pierre Dorion said MacArthur will be evaluated daily.
"We're at the point where we're heartbroken," the GM said, according to the Ottawa Sun's Bruce Garrioch. "I don't care about the hit. I care about Clarke."
MacArthur appeared in only four games last season due largely to concussion issues.
