The Philadelphia 76ers have been doing "due diligence" on Ricky Rubio for months.
The Minnesota Timberwolves could consider moving Rubio this offseason.
Philadelphia has been looking to part with either Jahlil Okafor or Nerlens Noel to balance out their roster.
Rubio signed a four-year, $54 million extension with the Wolves in 2014.
