Hal was diagnosed with cancer in May 2018 and was declared cancer-free in September.
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. Through eight appearances during the 2018 season, Hal made three interceptions and 13 tackles.
The 26-year-old safety started all 16 games for the Texans in 2017 before being placed on the reserve/non-football illness list before the season.
The LSU product has played for Houston since 2014, totalling nine career interceptions.
