Ben Simmons is apparently about to become the next recipient of a big commitment from the Philadelphia 76ers.

The All-Star point guard and the 76ers are negotiating a 170-million-U.S.-dollar, five-year extension, according to a person with knowledge of the situation who spoke to The Associated Press on condition of anonymity Tuesday because neither the team nor Simmons revealed any details publicly.

ESPN first reported the negotiations between Simmons and the 76ers. The deal will begin in the 2020-21 season.

Simmons will make about 8.1 million U.S. dollars this season, the last of his four-year rookie deal. Assuming the sides agree on what will be a full max, Simmons' salary for the following season would jump to about 29.3 million U.S. dollars and eventually rise to nearly 39 million U.S. dollars in 2024-25.

It's already been an off-season of big financial commitments for Philadelphia, which will sign Tobias Harris to a 180-million-U. S.-dollar, five-year deal and add Al Horford on a four-year deal that could reach 109 million U.S. dollars. Those deals cannot be finalized until the league's moratorium ends Saturday at noon Eastern.

Simmons' extension, when finalized, will push the amount of money committed to point guards this offseason – either via free agency or extensions – past the 1.2 billion U.S. dollar mark. Among the biggest winners of that sweepstakes: Portland's Damian Lillard got a 196-million-U.S.-dollar extension, Denver’s Jamal Murray got one for 170 million U.S. dollars and Simmons is on his way to getting the same.

Also Tuesday, the 76ers agreed with Shake Milton on a four-year contract and veteran James Ennis on a two-year deal. Those moves were confirmed by a person familiar with both sets of negotiations and who spoke to AP on condition of anonymity because they also cannot yet be finalized.

Also, restricted free-agent forward Dorian Finney-Smith has agreed to a three-year, 12-million-U.S.-dollar deal to re-sign with the Dallas Mavericks, sources said.

Free-agent guard Brad Wanamaker is returning to the Boston Celtics on a one-year deal.

Free-agent center Willie Cauley-Stein will sign with the Golden State Warriors, a league source told ESPN.

Free agent Jeff Green has agreed to a one-year, 2.5-million-U.S.-dollar deal with the Utah Jazz, free agent Jared Dudley has agreed to a one-year, 2.6 million U.S. dollar deal with the Los Angeles Lakers, and free-agent guard Emmanuel Mudiay has agreed to a one-year deal with the Utah Jazz, league sources told to ESPN.
