Update on why he didn't show up. Apparently it wasn't due to him missing a flight like it was first reported. The people who attended the charity event posted on the DH boards that Hayden had to fly to Toronto for a family emergency, something to do with Tove. Hayden apparently was in Denver already but had to get back home to Toronto very suddenly. It sounds like there must be something serious that happened for him to rush off like that.
No words yet whether Hayden will show up fpor the race in Denver on Sunday. Hopefully he does because then it means the family emergency got solved, but if he stays away it may mean something serious happened.
