The Tottenham winger's future remains in the balance as Real Madrid attempt to complete a world-record deal to take the 24-year-old to the Bernabeu, while reports have suggested Manchester United are set to enter the race.
Bale has not played for Spurs in nearly a month and is currently nursing a foot injury.
His club manager Andre-Villas Boas said the Welshman is unlikely to be fit for their Premier League opener against Crystal Palace, but he is currently part of Coleman's plans for Wednesday's friendly meeting with the Republic of Ireland.
A Football Association of Wales spokesman confirmed to Press Association Sport that Bale reported to the team hotel ahead of a training session in Newport on Monday afternoon.
But it is understood Bale is concerned about risking his fitness against the Republic with a potential big-money move on the horizon.
Aside from deciding to what extent Bale can be involved in his plans this week, Coleman also has injury concerns over Arsenal midfielder Aaron Ramsey (ankle) and West Ham defender James Collins (knee).
