Trade talks between the Minnesota Timberwolves and Miami Heat on Jimmy Butler reached the brink of completion before falling apart.

Minnesota had shared Butler's medical information with Miami late in the week.

Glen Taylor and Micky Arison became involved in the trade talks and there was hope of a call to the league to finalize it. But the Wolves moved to amend the framework of the trade and talks collapsed on Saturday.

Miami had softened on including guard Josh Richardson in versions of a possible deal for Butler, only to recoil once Minnesota pushed late for a sweeter return.

Talks could pick up again in the future.

Miami's believed willingness to pay Butler something in the neighborhood of a five-year, $190 million maximum contract next summer has played a part in Butler's enthusiasm in pursuing a deal there.
