According to the report, the Hawks will send the Nets a 2020 second-round pick originally from Portland and the rights to 2016 second-round pick Isaia Cordinier, who to date has remained in his native France.
Lin told the Nets website earlier this week that he has yet to participate in full-contact drills as he rehabs the injury. They took care of both late Thursday, trading Jeremy Lin to the Hawks and landing the Nuggets' 2019 first-round pick in a separate deal that shipped out Isaiah Whitehead.
Wojnarowski reports that as part of the deal, Atlanta and Brooklyn will exchange future second-round picks.
Lin joins rookie point guard Trae Young and veteran Dennis Schroder in a crowded back court with the Hawks. He has said he expects to be ready for training camp. During the 2016-17 campaign, Lin averaged 14.5 points and 5.1 assists for the Nets. He ruptured the patella tendon in his right knee during the Nets' opener last season, and while he was out Spencer Dinwiddie stepped in and became one of the NBA's most improved players.
The trade with the Nuggets was a salary dump for Denver.
Arthur, 30, got in just 30 contests in 2017-18, making one start.
