“He is dying,” the person said.

According to the report, the effects of the ailments are “worsening.”

“It’s basically a slide into oblivion. He’s frail. He’s physically and mentally limited. Around the clock care is required for him,” Monson wrote. “Although in the more recent past the old coach has been able to attend Jazz games, he will go no more.”

FLASHBACK: LEGENDARY NBA COACH JERRY SLOAN SAYS HE HAS PARKINSON'S DISEASE, DEMENTIA

Before Sloan went into coaching, he was a star forward for the Baltimore Bullets and Chicago Bulls from 1965 to 1976. He was a two-time All-Star selection and a six-time All-Defensive Team selection.

Sloan, 77, got his first head coaching job with the Bulls before the 1979-80 season and led the team to the playoffs during the 1980-81 season. He then joined the Utah Jazz as an assistant coach and served in that role from 1985 to 1988.

He was named the Jazz head coach during the 1988-89 season and stayed in that role until the 2010-11 season.

As a head coach, he recorded 1,221 wins and won the Western Conference championship in back-to-back years in 1996-97 and 1997-98 with teams led by Karl Malone and John Stockton. Unfortunately, the team ran into the Michael Jordan-led Bulls and lost in the NBA Finals both times.

Sloan was inducted into the Basketball Hall of Fame in 2011.
