Aarhus GF midfielder Benny Feilhaber hopes to be back in action before the end of March.
The former Derby County midfielder has an ankle injury which raised concerns about his fitness ahead of the US's World Cup campaign.
"I'm in Brazil doing my rehab, and there was a very positive prognosis," Feilhaber told Soccer365. "Nothing wrong with the ligaments, no breaks, no cartilage problems, only a bad sprain.
"I'm staying in Rio to do my rehab as me and my club both think this is the quickest way for me to get back to fitness," he added. "I hope to go back to Denmark by the end of next week and restart training by the end of the month at the latest."
