Former Liverpool, Aston Villa and Czech Republic striker Milan Baros said on Friday that he would postpone the time of his playing career at the end of the season.
"My head would like to continue, but the body said so," said Baros, 38, on the Banik Ostrava club website.
"I have had health problems for a long time and the body does not work the way it used to and the way I needed it," he added, complaining of Achilles tendons.
Baros, who also played for Portsmouth, Lyon and Galatasaray, gained prominence at Euro 2004, a tournament that ended as a top scorer.
Baros won the Champions League with Liverpool in 2005 and ended his international career after Euro 2012, having scored 41 goals in 93 games for the Czech Republic.
