Multiple reports claim Sabalenka intends to still play the tournament, although it has not been made official.
Police in Miami said the death was “an apparent suicide” and “no foul play is suspected”.
However, news outlet Telegraf reports Koltsov died of “a detached blood clot”.
Koltsov was part of the Belarus national team at the 2002 and 2010 Winter Olympics.
Russian club Salavat Yulaev announced the news on Tuesday.
“It is with deep sorrow that we inform you that the coach of Salavat Yulaev, Konstantin Koltsov, has passed away,” Russian club Salavat Yulaev said.
“He was a strong and cheerful person, he was loved and respected by players, colleagues, and fans. Konstantin Evgenievich forever wrote himself into the history of our club.
“May he rest in peace.”
The 42-year-old also spent time playing for the Pittsburgh Penguins in the National Hockey League, between 2002 and 2006.
In 2008, he won the Russian Super League title with his local club Salavat Yulaev, where he later returned as a coach.
Sabalenka and Koltsov have been together since 2021.
The 2024 Australian Open champion was defeated in the round of 16 at Indian Wells last week.
The 25-year-old is scheduled to play her opening match at the Miami Open on Friday.
