Early Thursday morning frontman Jon Bon Jovi posted the following message for fans on the group's website to give them the details about what happened: "Last night Tico Torres underwent an emergency appendectomy.

"Thankfully, the operation was a success and Tico is now recovering in the care of his doctors at the American British Cowdray Hospital. We'd like to thank the doctors, nurses and all the hospital staff who helped our friend through this difficult time.

"We'll remain here with Tico in Mexico City and will see him through his release. David and I spent the day with him at the hospital and Tico sends his thanks for all of your thoughts and prayers. He wants everyone to know that it was his desire to perform. He even promised the doctors he would come back for the surgery right after the show but the doctors prevailed.
