Greg Oden will meet with the Dallas Mavericks, Sacramento Kings and New Orleans Pelicans in Las Vegas this week.
The San Antonio Spurs and Miami Heat are also interested in signing Oden.
Oden hasn't played an NBA game since Dec. 5, 2009 after battling numerous major knee issues. Oden had his third microfracture knee surgery in February of 2012.
The Cleveland Cavaliers are no longer interested in signing Oden after reaching agreement with Andrew Bynum last week.
