San Francisco 49ers receiver Marquise Goodwin announced on Instagram after Sunday's game that his son died from complications during his wife's pregnancy.
His wife, Morgan, had to prematurely deliver the baby at 4 a.m. Sunday morning.
"Although we are hurt, I am grateful for the experience and grateful that God blessed me with a wife as courageous and resilient as Morgan," Goodwin wrote. "The pain (physically, mentally, & emotionally) that she has endured is unbelievable. Please Pray for the Goodwin family."
Goodwin played in Sunday's game against the New York Giants hours after the family tragedy and contributed in what became the team's first win of the season.
