Texans' David Quessenberry breaks bell after finishing chemo treatments

HOUSTON -- Texans offensive lineman David Quessenberry was so happy to finish chemotherapy at a Houston medical center that he exuberantly rang an end-of-cancer-treatment bell and broke it.

Quessenberry, who in 2014 was diagnosed with non-Hodgkin T-cell lymphoblastic lymphoma, had his last treatment Tuesday at the University of Texas MD Anderson Center. A plaque, featuring a bell and a cord, encourages patients who've completed chemotherapy treatment to clang the bell to sound their recovery efforts.

Quessenberry, who is 300 pounds, rang the bell with such enthusiasm that he yanked it off the wall -- with medical personnel cheering him on.

Quessenberry, who played for San Jose State, was a sixth-round pick in 2013 for the Texans. He was waivedby the Texans after the 2015 season but spent last season on the non-football illness list and remains on the team's roster.
