After scoring a lengthy touchdown in the first win of the season for the San Francisco 49ers, Marquise Goodwin posted to his Instagram account that he and his wife's baby boy died Sunday morning because of complications during her pregnancy.

Goodwin's 83-yard touchdown connection with C.J. Beathard was San Francisco's longest play of the season.

"Unfortunately, we lost our baby boy due to some complications, and had to prematurely deliver him early this morning around 4 a.m.," Goodwin wrote. "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.

"The pain (physically, mentally & emotionally) that she has endured is unbelievable. Please pray for the Goodwin family."

Goodwin blew a kiss to the sky before he crossed the goal line. He then knelt in prayer in the end zone as his teammates surrounded him.
