Miroslav Káčer

MŠK Žilina

Káčer began his football career at his hometown club MŠK Žilina. Aged 16, Miroslav made his debut for Žilina against Spartak Myjava on 13 July 2012. On his competition debut, he scored his first professional goal in a 4–1 win. Káčer was released from Žilina, as the club had entered liquidation, due to a coronavirus pandemic.

Viktoria Plzeň

On 6 May 2020, it had been announced that Káčer had signed for Viktoria Plzeň, along with Filip Kaša, who was also released from Žilina. They had re-joined their former coach from the Slovak club, Adrián Guľa, under whom they had won the Slovak Fortuna Liga in the 2016–17 season. The terms of his agreement with Viktoria were not announced.

Káčer was called up for two unofficial friendly fixtures held in Abu Dhabi, UAE, in January 2017, against Uganda and Sweden. He capped his debut against Uganda, when he was fielded in the 70th minute, when he substituted Roman Gergel. Slovakia went on to lose the game 1–3. He also appeared in the second match against Sweden, playing the first hour of the match, which Slovakia lost 0–6, before being substituted by Gergel.
