Clad in full Huskers gear, Hoffman, a cancer patient from Atkinson, Neb., took a 4th down handoff and ran 69 yards for the scrimmage's final touchdown.
Jack was diagnosed with cancer in April 2011 and has had two surgeries. He's now on a two-week break from a 60-week chemotherapy regimen.
What he was thinking when he ran onto the field, Jack said, "Scoring a touchdown." And when he broke free and scored? "It felt awesome," he said. And the crowd reaction? "Really awesome."
