Tiaguinho had learned that he would become a father just days before the Nov. 28 plane crash.
The son of Tiaguinho, a player for Brazilian side Chapecoense who was killed in the Nov. 28 plane disaster, was born on Thursday. His wife, Graziele, posted a picture of the newborn on Instagram.
The child is named after his father.
Tiaguinho was just 22 years old when LaMia Flight 2933 crashed en route to Colombia, where Chapecoense was to play Atletico Nacional in the first leg of the Copa Sudamerica. Seventy-one of the 77 passengers on board were killed, including 19 of the 22 players on the flight.
