Texans safety Andre Hal, who returned to the field for Houston last season after overcoming cancer, announced Tuesday that he is retiring.
"One thing I've learned in life is that change is inevitable and life goes through seasons," Hal wrote on Twitter. "This season of my life has come to an end. I will be retiring from the NFL. My health did not have anything to do with my decision. I am completely healthy."
Hal took the field for the first time since being diagnosed with Hodgkin's Lymphoma in May during the Texans' Week 7 road win over the Jaguars.
