The Chicago Blackhawks are inviting all fans to join forwards Ryan Hartman and Andrew Desjardins in the National Hockey League’s annual Beard-a-Thon during the 2017 Stanley Cup Playoffs. Seventy-five percent of the proceeds will benefit Chicago Blackhawks Charities, while the other 25 percent will benefit the Chicago Public Schools SCORE! program.

By joining the Blackhawks’ Beard-a-Thon, fans pledge to maintain their beard as long as the team remains in the playoffs. Fans who are unwilling or unable to grow playoffs beards can also pledge their beard grower. Only growers will be eligible for prize incentives.

First place overall will win four 100-level tickets to a 2017-18 Blackhawks regular-season home game and a postgame player meet-and-greet. Second place will win two 200-level tickets to a 2017-18 Blackhawks regular-season home game and postgame locker room tour. The third place winner will receive two 300-level tickets to a 2017-18 Blackhawks regular-season home game and a jersey signed by one current Chicago Blackhawks team member. There will also be challenges throughout each round so fans can win additional prizes.
