After the Toronto Maple Leafs were eliminated by the Boston Bruins in the first round of the 2019 Stanley Cup Playoffs, three players have been confirmed to undergo surgery in order for them to be at 100% next season.
Zach Hyman had surgery to repair a torn ACL in his right knee, Travis Dermott had surgery to repair what I am assuming is a dislocated shoulder or a torn rotator cuff, and Auston Matthews had surgery to remove surgical hardware, which is expected to be from breaking his femur back in 2013.
Zach Hyman
Hyman underwent surgery for a torn ACL in his right knee on April 25th and the expected recovery time is six months.
