A teen fan was injured at Wrigley Field Tuesday night when a piece of debris fell off the scoreboard, authorities and the team said. But it appears a bucket on the fan's head may have saved him from a more serious injury. 

The 19-year-old was at the field just before 9 p.m. in the 1000 block of West Addison when "a pin that holds the tile in place" fell on his head, officials said. The pin is about 6 to 8 inches in length, according to team spokesman Julian Green. 

Police said the teen was transported to Illinois Masonic Medical Center where he was listed in good condition. A non-criminal police report was completed, the department said. 

Green said the 19-year-old had a plastic bucket on his head, which "may have shielded some of the impact."  

The cause of the falling pin remained under investigation. It was not immediately known if it was dropped by a worker or became dislodged. 

The Cubs lost to the Diamondbacks 5-1 Tuesday.
