EDGE Analysis

Although NHL clubs are usually intentionally vague when it comes to injuries, the fashion in which MacArthur suffered his "upper-body injury" in Wednesday's game against Columbus made it clear that the 30-year-old forward was likely dealing with a concussion, a notion that was confirmed by general manager Bryan Murray on Tuesday. He has missed Ottawa's last two games with the ailment, and will need to complete the league's concussion protocol before being cleared to play. MacArthur's status for Thursday's game against the Devils is up in the air at this point in time.
