Quessenberry has spent the last three years in a fight against non-Hodgkin T-lymphoblastic lymphoma. The illness put his football career on hold, but he never gave up the dream. Finally cancer-free, Quessenberry will be in uniform when the Texans begin their preseason schedule against the Panthers (7:30 pm. ET on NFL Network).
Quessenberry's mother and girlfriend were among a group of family members who surprised him on the field before the start of the game.
