Frank Ocean will not return to the Coachella stage for the festival's second weekend, dropping out after sustaining two fractures and a sprain in his left leg.

In a statement provided Wednesday to TMZ, Frank's reps say, "After suffering an injury to his leg on festival grounds in the week leading up to weekend 1, Frank Ocean was unable to perform the intended show but was still intent on performing, and in 72 hours, the show was reworked out of necessity."

They continue, "On doctor’s advice, Frank is not able to perform weekend 2 due to two fractures and a sprain in his left leg."

Frank tells us, "It was chaotic. There is some beauty in chaos. It isn’t what I intended to show but I did enjoy being out there and I’ll see you soon."

TMZ broke the story, Ocean allegedly hurt his ankle on the festival grounds leading up to his show, causing some last-minute set changes ... so it appears things were much more serious than initially thought.

As we reported, fans were disappointed by the singer's performance at the festival Sunday night as he started an hour late -- there was also awkward pauses, fans could barely see Frank, and he didn't sing some of his most popular stuff. He also didn't sing some songs live, with a vocal track playing while he moved around the stage ... though the busted ankle might help to explain a few of those issues.

Now the question ... who will take his spot. As we reported, Blink-182 had a hugely successful return to the stage during the group's Friday show.

Calvin Harris also drew a massive crowd to the main stage when he hit the festival Saturday night.
