A fan in the right field bleachers was seriously injured after jumping over the right field wall before Thursday night’s game at Wrigley Field.

According to a source, security had warned the man about putting his foot on the railing, but he ignored it.

The Cubs said in a statement: “A fan was injured after attempting to jump onto the field from the Wrigley Field bleachers. The fan was taken by paramedics to Advocate Illinois Masonic Center. We are unable to provide further comment on his condition.”

The Cubs did not release the man’s name.

The man was dressed in shorts and sneakers, and was face down on the warning track after the jump before being attended to by a medic. After being turned on his back, a brace was put on him to stabilize the neck before he was put on a cart and taken off the field.

Cubs outfielder Albert Almora Jr. and pitching coach Chris Bosio also went out to the outfield to check on the man.
