Big man Amir Johnson, formerly of the Toronto Raptors, is signing a two-year deal with the Boston Celtics worth $24 million, according to Adrian Wojnarowski of Yahoo! Sports:

Free-agent forward Amir Johnson has agreed to a two-year, $24 million deal with the Boston Celtics, league sources told Yahoo Sports.

 

Agent Kevin Bradbury of BDA Sports completed the deal Wednesday with Boston GM Danny Ainge.

 

Johnson, one of the best forwards on the market, departs after six seasons with Toronto. He gives Boston a long, athletic and experienced dimension that it needed in its frontcourt.

 

Johnson averaged 9.3 points and 6.1 rebounds in 75 games for the Raptors last season.

 

The Celtics can’t officially sign Johnson until July 9 when the NBA’s free-agent moratorium ends.
