A portion of Denver's Mile High Stadium caught fire on Thursday.

The fire burned in a portion of the club level on the east side of Empower Field at Mile High. The Denver Fire Department responded at about 2:15 p.m. MDT to a fire that began in a construction zone in that part of the stadium.

There was a stadium tour underway at the time, and the group -- as well as employees who were working in that part of the stadium -- was evacuated from the stadium. No injuries were reported.

A Denver Fire Department spokesman said the fire covered "over 1,000 square feet'' and began on a suite level -- the fourth level -- of the stadium and then spread into seats in the third level.
