His Majesty King Juan Carlos of Spain will attend Real Madrid's Champions League semi-final second-leg clash against Borussia Dortmund tonight.
The 75-year-old has been given permission by his doctors to attend the game at the Santiago Bernabeu.
This will be Juan Carlos I's first appearance in public since undergoing surgery for a herniated disc on March 3.
Madrid lost the first leg 4-1 in Germany last week.
