Nadal is scheduled to face compatriot Carlos Alcaraz in an exhibition match in Las Vegas on 3 March before making his ATP comeback at Indian Wells a few days later.
Speaking to Spanish broadcaster La Sexta, Nadal said he was unsure of how many tournaments he would be able to compete in this year.
In addition to the three remaining Grand Slams – the French Open, Wimbledon and US Open – the Olympic Games also take place this summer in Paris.
“I don’t know which events I have left to play but between you and me, it’s not going to be many,” said Nadal, who won gold at the 2008 Games in Beijing.
“[Roland Garros] will be one of my goals. I’d like to play at the Olympics as well. It’s not something I can confirm right now, but I hope I will… I think I will.”
In May, after being forced to miss the French Open for the first time in 19 years, Nadal said 2024 would “probably” be the final year of his career.
