Adams joined Bournemouth from Leeds United in a deal worth more than £20 million ($38.6 million) last year but endured an injury-affected debut season at the Cherries.

He has only made three Premier League appearances, a total of 118 minutes, and will sit out the start of 2024-2025 after aggravating a back issue at the Copa America.

Adams featured in all three of his country's games at its home tournament, but it crashed out in the group stage.

Bournemouth boss Andoni Iraola now expects to be without his man in the early stages of the campaign.

"He finished the season with an injury in his back," Iraola said. "He wanted to play the Copa America because it was very important for him, but he had restrictions and was still in pain, so two days after they were knocked out, he had surgery.

"He is out for some time. It is difficult to say how long but he won't be fit for the start of the season. But September? October? I don't know."

Asked why Bournemouth did not prevent Adams from linking up with United States, Iraola added: "It was not our choice.

"It is a decision for the nations, who are allowed to select players, and he wanted to play thinking the injury would get better but he felt it was getting worse."
