Trail Blazers head coach Terry Stotts told reporters Anthony will likely start at power forward for Portland for the foreseeable future.
Anthony last played in an NBA game on Nov. 8, 2018, during his 10-game stint with the Houston Rockets. He averaged 13.4 points per contest during that stretch but was inactive for the rest of his time with the team.
The 10-time All-Star was then traded to and waived by the Chicago Bulls, and he remained unsigned until this week when he agreed to a non-guaranteed $2.15 million deal, per Shams Charania of Stadium and The Athletic.
Anthony spoke about joining the Trail Blazers on his YouTube page:
"I always kept my eye on Portland," Anthony said (h/t NBA.com). "It just didn't work out at other times. But now it seems like a perfect opportunity. I just look at that team and say, 'This is what I can bring, this is where I can help.' It can only work if all parties see it the same way."
Portland had high expectations after reaching the Western Conference Finals last season, but the team is just 5-9 to start this year.
Anthony, who averaged more than 20 points per game in each of his first 14 seasons, will hope he can provide a jolt to the underperforming squad.
