Among those stepping up: actor James Denton, who was on "Desperate Housewives."
Video of Jack Hoffman's run during Nebraska's spring football game was an Internet hit. The Upper Deck Co. issued a card for Jack, with signed blow-ups for his foundation to auction off.
The winning bidder for the first card declined to pay, saying he hadn't authorized the $6,100 bid. Jack's father, Andy Hoffman, says news coverage prompted three buyers to offer $10,000 each for a signed card.
Denton lives in suburban Minneapolis, and the Hoffmans travelled there to meet him Tuesday. They are from Atkinson, Neb.Suggest a correction
