Anthony, 35, has to complete a physical with the Blazers before the one-year, non-guaranteed contract is finalized. That could come as soon as Saturday, league sources said.
The Blazers are starting a six-game road trip that includes a game Saturday against the San Antonio Spurs before Monday's game in Houston.
Beset by frontcourt injuries, including to power forward Zach Collins and center Jusuf Nurkic, Portland has struggled to a 4-8 start this season. The Blazers reached the Western Conference finals a season ago.
The Blazers are hopeful that Anthony can bring an immediate presence to a locker room that needs a jolt. Anthony, a 10-time All-Star and future Hall of Famer, hasn't played since a 10-game run with the Rockets that ended early in the 2018-2019 season.
