The Dallas Stars were without head coach Pete DeBoer for Monday night's second preseason game. DeBoer did not travel with the team on their road trip to Denver to take on the Colorado Avalanche,
as he had surgery to have his appendix removed, per a report from Mike Heika of DallasStars.com. The medical staff had found a problem with DeBoer's appendix during his annual physical at training camp, necessitating the surgery.
