Fans can breathe a sigh of relief: it turns out Carlos Santana‘s collapse on stage on July 5th was due to heat exhaustion and dehydration.

Santana stunned the crowd after fainting while performing in Independence Township, Michigan at the famed Pine Knob Music Theatre. Last night’s show (July 6th) in Burgettstown, Pennsylvania at The Pavilion at Star Lake was postponed and will be rescheduled for August 4th.

Santana’s wife and drummer Cindy Blackman Santana posted a Facebook message to fans from the couple writing: “Hi Everyone! Carlos & I thank you so much for your prayers, love, care & concern for him! Please know that he’s resting and doing very well! He was diagnosed with heat exhaustion & dehydration. . . it was 100 degrees on stage and 114 under the lights so that coupled with not enough water is what caused the issue. He’ll be as good as new soon! Thank you again and we love you! Cindy & Carlos.”
