USA Today Sports

Game 6 of the Eastern Conference Finals was played under difficult circumstances for Al Horford.

ESPN Deportes first reported that the grandfather of the Boston Celtics big man, José Reynoso Núñez, passed away at 81 on Thursday, a day before the Heat forced a seventh game with a 111-103 win at TD Garden.

Núñez, Horford's maternal grandfather, was suffering from "various ailments," ESPN reported.

According to ESPN, Horford traveled separately from his teammates to Game 5 in Miami so that he could be with his family in Atlanta, where Núñez had been spending his final months alongside other family members prior to returning to his native Puerto Plata, Dominican Republic. A funeral for Núñez was held Saturday, ESPN reported.

Horford's sister, Anna, confirmed the news of her grandfather's death via Twitter.

It is unclear whether or not Horford was able to travel to Puerto Plata, also his hometown, for the funeral. He is expected to play in Game 7 for the Celtics on Sunday at 8:30 p.m. in Miami, where he'll attempt to earn his first trip to the NBA Finals after 140 postseason games without one, the most of all-time.
