Tyler Johnson has signed his four-year, $50 million offer sheet with the Brooklyn Nets.

The Miami Heat have three days to match the terms on the sheet to retain Johnson.

The deal includes $18 million-plus and $19 million, plus "poison pill" provisions, in years three and four of the deal designed to severely puncture the Heat's salary cap.

Johnson made $507,000 in his second NBA season for the Heat in 2015-16. 

David Aldridge reported Miami reached out to Johnson shortly after Dwyane Wade agreed to sign with the Chicago Bulls about signing a deal with them that's not as punitive cap-wise.
