Tottenham defender Ben Davies has joined up with the Wales squad after originally being ruled out of the European Qualifiers against Croatia and Hungary.
Davies, 26, had been due to have groin surgery following Spurs' involvement in the Champions League final against Liverpool in Madrid on Saturday, where he was an unused substitute.
But a Football Association of Wales statement said: "Ben Davies has joined up with the Wales squad this morning as his scheduled treatment has been postponed."
Davies last appearance came in Spurs' final Premier League game of the season, a 2-2 draw at home to Everton, when he played the full 90 minutes.
Wales will play Croatia in Osijek on June 8 before taking on Hungary in Budapest on June 11. They won their opening game against Slovakia in March.
