The 20-time Grand Slam winner has been struggling with a back issue since the build-up to the Australian Open and was forced to skip Spain's ATP Cup ties earlier this month.
"Once I got back to Spain I visited my doctor and together with my team they've advised not to play this upcoming week."
"It's not that I'm in a really bad way, but I'm also not alright in the sense that I can't play either," Nadal told Spanish television channel Movistar+.
"I've improved a little but I'm not in a position where I can go and play a game at full intensity."
