Former NBA All-Star and reigning Big3 MVP Joe Johnson is in Philadelphia preparing for a workout Thursday with the 76ers, a source told ESPN's The Undefeated.

Johnson, 38, also is receiving interest for potential workouts from the LA Clippers, the Milwaukee Bucks, the Denver Nuggets and the New Orleans Pelicans. Pelicans coach Alvin Gentry and executive vice president David Griffin watched Johnson play in the Big3 league in New Orleans last week.

Johnson was a seven-time NBA All-Star who averaged 16 points, 4.0 rebounds and 3.9 assists per game from 2001 to 2018, playing for seven teams.

He most recently played in the NBA during the 2017-18 season with the Utah Jazz and Houston Rockets.

Johnson returning to the NBA through the Big3 would be huge for the three-year-old league, because it has not previously had a player sign with the NBA.

Johnson and the Triplets face the Killer 3s for the Big3 championship on Sunday in Los Angeles.

Johnson was named MVP of the 2019 Big3 season after leading the league in points (175), assists (31), 4-point shots made (four) and total field goals (63) and finishing second in 3-pointers made (16).

"Joe Johnson playing in the Big3 has been a dream come true for basketball fans around the world," league founder Ice Cube told The Undefeated.
