Former Portland Trail Blazers center Ruben Boumtje-Boumtje is retiring immediately because of a heart condition.

Boumtje-Boumtje’s latest club Bayern Munich says the 33-year-old player decided to retire after a medical exam uncovered “new irregularities” that could have later consequences. The club gave no details Wednesday.

Boumtje-Boumtje says his “health and family are of the greatest importance.”
