Yaya and Kolo Toure have decided to stay with the Ivory Coast squad in Brazil following the death of their brother, a team spokesman has confirmed.
Ibrahim Toure, a 28-year-old player with Lebanon-based Al Safa, died in Manchester on Thursday.
Following uncertainty over whether the brothers would leave Brazil to be with their family, the Ivorian Football Federation (FIF) spokesman told Press Association Sport they would remain at the World Cup.
"The Toure brothers, Kolo and Yaya, have decided to stay with the team," he said. "They are not leaving Brazil."
Ivory Coast face Greece in Fortaleza on Tuesday, when a win would see them qualify for the round of 16.
Manchester City midfielder Yaya Toure played in the 2-1 defeat against Colombia, while Liverpool defender Kolo Toure was an unused substitute.
Blatter also extended his sympathies on Twitter.
Very saddened to learn of the death of Oyala Ibrahim Touré, younger brother of Yaya & Kolo Touré. My deepest condolences for your loss. RIP.- Joseph S Blatter (@SeppBlatter) June 20, 2014
