Tyrann Mathieu's grandmother died earlier this week.
The Arizona Cardinals safety took to Twitter on Tuesday to mourn her and celebrate her life.
His grandmother, Marie Spellman Mathieu, helped raise him.
In one tweet, Mathieu said that he wears his No. 32 in honor of his grandmother.
"In essence she is my mother," Mathieu told ESPN last week. "She always kept me strong. She was always that ear I needed. When everybody else didn’t really understand me, she always did. I guess all grandmothers are like that, but to me she was more like a mother because she fed me bottles, when I cried she rocked me to sleep.
