"An act of violence occurred outside the stadium at tonight's football game between Central Catholic and Whitmer," the statement read.
"At this time, we know that three people were shot, including two adults and one Whitmer student and were transported to a local hospital to be treated for their injuries.
"No guests were injured in the evacuation and we could not be prouder of our students, staff, Whitmer fans, and our guests from Central Catholic."
According to The Toledo Blade, two of the victims were taken to ProMedica Toledo Hospital, while the third was rushed to Mercy Health St Vincent Medical Centre.
A witness told police that two people wearing black ski masks fired the shots, The Toledo Blade reported.
"We are deeply saddened that a fun rivalry tonight was disrupted by an act of violence in the streets surrounding our event," Washington Local Schools superintendent Kadee Anstadt said in a statement.
"What we know at this time is limited, and we will not speculate until further details are known.
"An event like this is every school district's worst nightmare, and we ask that you keep both Central and Whitmer in your thoughts as we attempt to figure out this atrocious act."
