BROOMFIELD, Colo. — Broomfield High School's head football coach resigned after a district investigation into allegations of inappropriate behavior involving "several Broomfield High School students."
A letter from the school's principal and athletic director sent to families on Monday says Blair Hubbard "will not return to his coaching and teaching positions at Broomfield High School."
Hubbard resigned his position with Boulder Valley School District on Monday.


The letter says that a "complete and adequate investigation" was completed on Thursday.
The district said their investigation into the allegations included 53 witness interviews.
"We shared the report with the employee last week, and accepted the employee's resignation today," said a district spokesperson. "The employee has the full investigation report, but BVSD does not believe it is a public record that BVSD can share."
No other details about the specific nature of the allegations was released.
The Broomfield Police Department also conducted an investigation into Hubbard. In a statement, the district said that "detectives conducted a thorough investigation and found Hubbard did not engage in any criminal behavior. No charges were filed and the case has since been closed."
Hubbard had been on leave since Dec. 15, according to a district spokesperson.
He had worked for the school district for over six years. Broomfield High School's football team won the Class 4A state championship in 2022.
