He later apologised and accepted the fine. In his last match for the reserves, he scored a hat-trick in the team's 5–2 away win at TuS Mechtersheim. Shortly thereafter, he permanently returned to first-team action. In Kaiserslautern's opening match of the 2008–09 season, a 3–3 away draw at Mainz, Jendrišek came on as a half-time substitute after the team went 3–0 down in the first half and went on to score two goals in two minutes midway through the second half to level the score. He scored another brace on 17 November 2008 in Kaiserslautern's 6–0 win over Hansa Rostock and went on to finish the 2008–09 season as the club's top goalscorer, scoring 14 goals in 33 league appearances. In the 2009–10 season, he was again Kaiserslautern's top goalscorer in the league, netting 15 goals in 31 appearances as the club finished top of the 2. Bundesliga to return to the top flight after four years. On 29 April 2010, it was announced that Jendrišek will leave Kaiserslautern at the end of the 2009–10 season, moving to Schalke on a three-year contract. Jendrišek spent most of his time with Schalke on the substitutes' bench. In 2010, Schalke brought two new top strikers into the club, Klaas-Jan Huntelaar and Raúl, limiting Jendrišek's opportunity for first-team football. On 19 January 2011, it was therefore announced that he would leave the club for fellow Bundesliga side Freiburg in a €900,000 deal. Jendrišek scored his first goal with Freiburg in a 3–0 victory over VfL Wolfsburg on 27 August. After two years in Freiburg, he signed with 2. Bundesliga club Energie Cottbus. On 18 August 2014, he signed with Spartak Trnava on a year contract. On 12 January 2015, he signed with Cracovia as a free transfer. On 26 June 2017, he signed a two-year contract with Greek Super League club Xanthi, on a free transfer again. On 26 August 2017 he scored his first goal with the club in a 2–0 away win against Platanias and on 19 November was scored a brace in the 900th game of his club in Super League sealing a 2–0 home win game against rivals Panionios.
