Kevin Durant and his representatives have added free-agency meetings with the Boston Celtics, Miami Heat and Los Angeles Clippers, a league source confirmed to ESPN's Chris Broussard.
The three additions join previously reported plans for face-to-face talks with the Golden State Warriors, San Antonio Spurs and Oklahoma City Thunder.
Durant is also considering meeting with the New York Knicks but has no plans to talk to his hometown Washington Wizards, the source said.
The Wizards were already doubtful about their chances of signing Durant, a team source told ESPN's Britt McHenry.
Durant, 27, has spent his entire nine-year career with the Thunder franchise. He averaged 28.2 points per game last season and led the Thunder to within one victory of the NBA Finals.
NBA free agency officially begins July 1.
