That's according to ESPN's Adrian Wojnarowski, who claims the Timberwolves even shared Butler's medical informational with the Heat, suggesting a deal was close.
Timberwolves owner Glen Taylor and Heat owner Mickey Arinson reportedly had become involved in the discussions and all indications were a trade was going to be reported to the league office.
However, the Heat retracted their initial offer after Minnesota tried for a "sweeter return" for the 29-year-old.
Talks could pick up again in the future. The talks could re-start, but the breakdown means it will likely take more time for the Wolves to deal Butler and the ambiguity around his status could remain into the regular season.

The only difference between Collins and the other 49 Republicans voting yes is the way she held off from announcing her decision. In a second tweet, she cautioned that she was "not making any announcements" but was "deeply disappointed" in Collins' vote.
Butler made it clear last month after showdown talks with Tom Thibodeau that he wants to leave.
He is entering the fourth season of a five-year, $92.3 million contract he signed with Chicago in 2015, but he can enter the free agent market next summer by opting out of the final year. The report also said the Rockets have been aggressive in trying to acquire Butler while Yahoo reported the Clippers have interest in trading for Butler.
Butler has been away from the team since being given permission to skip media day and has been rehabbing from offseason surgery on his right hand. Miami always desires to be a destination for the NBA's elite players, and having Butler in tow helps with that goal.
Minnesota must trade him while they have the chance.
