Houston Texans David Quessenberry Completes Chemo, Breaks Victory Bell!

When Houston Texans offensive tackle David Quessenberry finished his last round of chemotherapy after a 3 year battle, he got to ring the victory bell at the hospital ... AND BROKE THE DAMN THING!

It's actually an awesome video ... Quessenberry has been fighting Non-Hodgkin's lymphoma since he was diagnosed in 2014 ... a year after he was drafted into the league.

Now, more than 1,000 days after he began his battle ... Quessenberry completed his last chemotherapy treatment at MD Anderson cancer hospital in Houston and got to ring the bell to announce to the world that he's well on the road to recovery!

He rang it so damn hard it broke!

Quessenberry commented about it, saying, "This bell, just like cancer, never stood a chance."
