Lowry is believed to be available ahead of the March 25 trade deadline.
A source told Pompey that Lowry, a Philadelphia native, would prefer to play for the Sixers.
But he has also has ties with the Clippers — as former teammates Kawhi Leonard and Serge Ibaka both play for LA. He is also reportedly tight with Clippers coach Tyronn Lue and assistant Chauncey Billups.
The Miami Heat also have an interest in Lowry, per Pompey.
Lowry, Leonard and Ibaka won a championship with the Raptors in 2019. And after nine seasons in Toronto, Lowry is on an expiring contract.
If Lowry were to remain with the Raptors beyond the deadline, the Sixers, Clippers and Heat would be among the teams he would consider in free agency, Pompey noted.
