Tottenham star has undergone a hernia operation.
Davies was due to have the surgery in early June, before it was delayed, BBC Sport reported.
This enabled Davies to feature at international level for Wales.
This did not work out well, with Wales losing both Euro 2020 qualifiers and Davies' performance against Hungary being panned.
Davies last night sent a message on Instagram from his hospital bed, explaining that the operation went well.
Davies should be recovered in time to feature for Tottenham in pre-season.
The 26-year-old made 20 Premier League starts from a possible 38 last season, with Danny Rose playing more of a role than the previous year.
