Brand is expected to be officially introduced by the team on Thursday, Wojnarowski added.
The 39-year-old has quickly transitioned from former player to the Sixers' front office, beginning as a player-development consultant following his retirement in October 2016.
Brand was named the general manager of the team's G League affiliate Delaware Blue Coats in August 2017 and the 76ers hired him as their vice president of basketball operations a year later on Aug. 27, 2018.
In 17 years in the NBA as a player for the Chicago Bulls, Los Angeles Clippers, 76ers, Dallas Mavericks, and Atlanta Hawks, Brand averaged 15.9 points and 8.5 rebounds on 50 percent shooting.
The first overall pick in the 1999 draft, he was named Rookie of the Year in the 1999-00 season and was an All-Star in 2001-02 and 2005-06.
