SFC Opava

Kozák started his career in 2001 with Czech club Slezský FC Opava, first playing with its youth teams before being promoted to the first team in 2007. Considered a promising talent, Kozák was a prolific goalscorer in the Czech Second Division with Opava. In October 2007, he scored his first hat-trick, coming in a 5–1 Opava win against FC Zenit Čáslav in the second division. In January 2008, Kozák went on trial with English Premier League club Portsmouth, however he did not join Pompey.

Lazio

Kozák joined Lazio in July 2008, signing a five-year contract, with rumours that Lazio club president Claudio Lotito paid a €1.2 million ($1.8 million) transfer fee. He later went on loan to Serie B side Brescia in the 2009–10 Serie B to gain experience and regular playing time. On 26 September 2009, Kozák scored his first goal in Italy against Grosseto. At the end of his loan spell, Kozák returned to Lazio and scored his first goal for the Biancocelesti on 18 September 2010, which turned out to be the winner against Fiorentina. On 16 January 2011, he netted the deciding goal against Sampdoria after coming on as a 77th-minute substitute, before scoring two goals on his full club debut two weeks later, again against Fiorentina. Having achieved four goals in nine starts for Lazio of which four goals came in January, Michal Bílek, manager of the Czech Republic, called Kozák up to the national team and announced he would make a special trip to the Stadio Olimpico…

On 14 November 2012, Kozák debuted for the Czech Republic national football team in a friendly match against neighbours Slovakia, coming as a substitute for David Lafata in the 67th minute. He scored his first goal in a 1–1 friendly draw against Hungary on 14 August 2013.
