EDGE Analysis

MacArthur was minus-6 with 16 goals and 20 assists last season. His campaign was shortened by 20 games in large part to a concussion that sent him to IR for more than a month. MacArthur is a dual threat in the sense that he can score goals and also set up a fair share of them himself. The winger averaged 2:58 on the ice during power-play situations and had six goals and four assists that that man advantage.

MacArthur acknowledged he suffered a hip flexor injury during the postseason series with the Canadiens, TSN.ca reports. The injury appeared to occur in Game 5, when he left the match prematurely with what the team termed as a "lower-body injury." MacArthur was ultimately able to suit up for Game 6, logging 20:39 of ice time and supplying five shots on goal and seven hits in the series-ending loss. He'll take the next several months off to recuperate from the injury, but should be fully healthy by the time training camp arrives.

However, it appears the injury was minor enough that he'll give it a go as the Senators look to stave off elimination once again.
