MIAMI — The Miami Heat’s extension agreement with Pelle Larsson comes with a unique twist — Larsson now stands as the lone player on the roster who cannot be dealt this season.

Because Larsson’s four-year, $60 million extension agreement exceeds the limitation parameters of a sign-and-trade agreement, a six-month trade restriction is triggered.

With Larsson to sign his extension this week, that six-month restriction takes him beyond the Feb. 11 NBA trade deadline.

Because of the length and total dollars of the extension, Larsson would have had to sign his agreement by Aug. 11 to be trade eligible this season.

The two components in Larsson’s extension that trigger the six-month trade restriction are that he received a package for more than three years and received raises in excess of 5% per season (in his case 8%).

Larsson’s extension differs from the four-year., $62.5 million extension signed last year by Nikola Jovic because Jovic was coming off the rookie scale for first-round picks. Jovic was eligible to be traded after last year’s agreement, but with a “poison pill” restriction that would have had him going out for more money than he could have been replaced on the Heat’s cap.

In contrast to Larsson, even though Andrew Wiggins agreed to a Heat extension ahead of this coming season, the two-year length of that agreement and decline in salary did not trigger the six-month no-trade provision.

Four players on the Heat roster currently also carry trade restrictions, with players signed as free agents to standard contracts not eligible to be dealt for three months or Dec. 15, whichever comes later.

That restriction is in place with Simone Fontecchio, Tim Hardaway Jr., Klay Thompson and Nick Richards.

A pair of Heat restrictions have already been lifted, with Giannis Antetokounmpo and Bobby Portis eligible to be aggregated in a trade two months after their July 6 acquisition from the Milwaukee Bucks.

While those two never figured to be in play, Larsson nonetheless stands as the lone Heat player currently ineligible to be traded this season.

The next contractual moves for the Heat could be contract extensions with Davion Mitchell, who otherwise would become a free agent next summer, and Antetokounmpo, whose window for a maximum extension opens Jan. 6, six months after his acquisition from the Milwaukee Bucks.

Larsson still must pass a physical before he can sign his extension.
