Boom Port Adelaide recruit Jason Horne-Francis has undergone surgery to fix a problem in the arteries behind his knees.
The Power said on Friday they were aware of the issue before recruiting Horne-Francis earlier this month in an AFL mega-trade involving four clubs.
They also expect the midfielder to be ready for the start of next season.
The operation involved decompressing the arteries behind his knees.
"When the club committed to pursuing Jason during the trade period, we were made aware he had been managing ongoing, at times debilitating, pain in both calves and feet throughout the 2022 season," Port's head of medical services Tim O'Leary said.
"Our subsequent investigation revealed he had significant compression of the arteries in the back of his knees, causing blockage to the blood flow to his lower legs.
"Following consultation with numerous specialists ... we decided it was best for Jason's health, and ongoing football performance, that he have the surgery now to release the pressure on the arteries and restore normal blood flow to his lower legs.
"He is now recovering well ....with a view to being ready to play in the 2023 season opener."
Horne-Francis, the 2021 No.1 draft pick, played 17 games this season for North Melbourne.
He then stunned the Kangaroos by requesting the trade to Port.
"It's been tough, and there have been challenges throughout the year. And for my part, I probably haven't done everything right either," Horne-Francis said after moving back to his home city.
"As a 18-year-old kid moving out of home to Melbourne, it was tough and I didn't get everything right. I think it's going to help me going forward."
