Liz Rosenberg of Warner Bros. Records said in a statement that the "Material Girl" singer suffered minor injuries and bruises when the horse she was riding on was startled by photographers, CNN said Sunday.
Rosenberg said the photographers involved in Saturday's incident jumped from bushes to photograph Madonna, 50, who was visiting with friends.
An unidentified spokeswoman for the pop singer told the New York Post while Madonna was released from the hospital following the incident, she will remain under medical supervision and undergo more tests to assess her condition.
The incident marked the pop singer's most recent horseback injury. Madonna broke her collarbone, hand and three ribs in 2005 when she fell off a horse's saddle while celebrating her 47th birthday with her family in England.
Madonna is set to begin a summer tour in Europe starting July 4 in London.
