Clarke MacArthur is dealing with another head injury, and this one occurred in a controversial manner.
The Ottawa Senators forward was diagnosed with a concussion Sunday after being drilled by defenseman Patrick Sieloff in training camp.
Sieloff hit MacArthur from the blind side along the boards, and Bobby Ryan was quick to go after the 22-year-old blue-liner.
Ryan clearly wasn't pleased with the hit at the time.

MacArthur appeared in only four games last season due largely to concussion issues.
