Hyman suffered a torn ACL in the club's first-round playoff series against the Boston Bruins. He played through the injury for three games. The 27-year-old was given a six-month recovery period after undergoing surgery on April 29.
Speedster Kasperi Kapanen has been practicing in Hyman's place at left wing on a line with John Tavares at center and Mitch Marner at right wing. Kapanen said he's ready to fill the workhorse void left by Hyman.
"I'll let them do all the nice things and I'll do the dirty work," Kapanen said.
Kapanen, Tavares, and Marner spent just over six minutes together at five-on-five a year ago, but the results were impressive in the short sample size. The trio outscored the opposition 3-1 and held a 12-8 shot-attempt advantage, according to Natural Stat Trick.
Kapanen, a natural right winger, will be playing out of position. The 23-year-old set career-highs with 20 goals and 24 assists a year ago.
Meanwhile, a glut of defensemen, including veterans Ben Harpur, Jordan Schmaltz, Martin Marincin, Kevin Gravel, and Justin Holl, and youngsters Rasmus Sandin and Timothy Liljegren, will jostle for minutes in Dermott's absence.
