Career
He turned professional in 2005. At the 2011 Paris–Nice, Kišerlovski crashed on a slippery downhill and slid underneath a parked truck, being caught underneath it for several minutes and needing eight stitches. On Stage Fourteen of the 2012 Tour de France Kišerlovski came off the worst when the road was sabotaged with tacks.
Kišerlovski crashed, breaking his collarbone, and was left having to abandon the race.
The injury forced him to miss 2012 Summer Olympics in London. Kišerlovski left Astana at the end of the 2012 season, and joined RadioShack–Leopard on a two-year contract from the 2013 season onwards.
In September 2014 it was announced that he would be joining Team Tinkoff-Saxo at the start of 2015 on a two-year contract with a view to riding as a domestique for riders such as Alberto Contador. He is the brother of fellow racing cyclist Emanuel Kišerlovski.
