Bob, thank you for letting siouxsports.com know. As a father, I cannot imagine how difficult this is for both parents and son.
Be strong. Keep the faith. As my 4-year old daughter said at the X in 2001, with the Sioux trailing by 3 with 4 minutes left, "I think we're going to score 3 and tie it up". Kids carry tremendous faith. That will carry them through, and you'll strengthen each other.
Godspeed.
