Laurent Ciman rejoined his Montreal Impact teammates on Monday, three days after Belgium was eliminated from the Euro Cup.
Wales defeated Belgium 3-1 on Friday in the quarterfinals of the European soccer championship.
Ciman left the Impact in mid-May to train with Belgium, and he had played with the national team in nine matches since 2010.
Ciman was also the 2015 MLS defender of the year.
Didier Drogba was also at practice on Monday, after missing Saturday's game against the New England Revolution because of a thigh injury.
Drogba is expected to start in the next match, this coming Saturday in Salt Lake.
