Bull riders and their fans are mourning the passing of professional rider Mason Lowe.

CNN reports the rider died this week at a competition in Denver, Colorado when he fell from a bull and the animal trampled him.

The Professional Bull Riders Association says the bull stepped on Mr. Lowe's chest, causing damage to his heart. He died at the hospital.

Mason Lowe was ranked as the eighteenth best bull rider in the world. The 25 year-old has been riding professionally for seven years.

"Our entire rodeo family and every member of the Stock Show community is saddened by the loss of bull rider Mason Lowe," National Western Stock Show President and CEO Paul Andrews said in a public statement.

"Our hearts and thoughts are with the Lowe family, his fellow bull riders and the entire PBR organization."

PBR CEO Sean Gleason said the bull Mr. Lowe was riding would continue in competition for the remainder of the National Western Stock Show.
