Career
In his country, Jonas never played in higher than the third division. On 15 June 2005, the free agent joined Scottish Premier League side Falkirk alongside compatriot Vítor Lima, being discovered by the club"s player-coach Russell Latapy, who spent several seasons in Portugal as a player. On 29 May 2006 Jonas was awarded a new one-year contract with the Bairns, after having played in 37 competitive games in his first season.
He would never appear, however, for the first team again, leaving in December 2007 and returning to Portugal.
