Pau Gasol says he is considering not playing at the Olympics because of the Zika virus.
The Spanish basketball player says there is too much uncertainty about the situation in Brazil and anyone going to Rio de Janeiro for the games should "think about" whether it's worth the risk.
He says other Spanish athletes have also expressed their concerns about the virus and are also considering skipping the games. He did not name the other athletes.
Gasol says Olympic committees and health organizations must come forward with more information about the risks athletes could be facing if they decide to compete in Rio.
