The 29-year-old centre-back has made 19 appearances for his country, scoring twice, having previously played for them at under-19 and under-21 level as well. His first international goal came in a World Cup qualifier against Lithuania in September 2013. The move to England marks his second spell in British football, having previously been a part of the Inverness side that won the Scottish First Division in the 2009-10 season.
Born in the Latvian capital of Riga, Nauris featured for a number of smaller Baltic sides during the beginning of his career. His first club was Latvian side FC Daugava, whom he spent a season with before joining Lithuanian side FK Siauliai for the 2008 season. He returned to Latvia for the 2009 season, joining FC Tranzit, where he made 17 appearances before moving on loan to Inverness in the summer of 2009. He made his debut for them in a Scottish League Cup match against Annan Athletic, scoring his first goal for the club in the next round against Albion Rovers.
In total he made 39 appearances for Inverness as they won the Scottish First Division, with Nauris also contributing four goals over the season. Upon returning to Latvia that summer he joined FK Ventspils, spending six months there before moving on to Slovakian side Spartak Trnava. Injuries plagued him significantly during his time there, and soon he was on the move again joining Jurmala for his first spell with the club. He made over 50 appearances for them in a period which saw him make his international debut in the 2012 Baltic Cup, where he helped Latvia to win the tournament in his first two games for his country. In the summer of 2013 Nauris joined one of Latvia's most successful teams, Skonto Riga, on a three-year deal. Unfortunately financial difficulties at the club saw him again limited to just a six month stay. He subsequently moved briefly to Switzerland, playing for FC Aarau, before returning to Jurmala for a second spell in early 2015.
