A simulated "large-scale terrorist attack" will be staged at Fenway Park this weekend.

On Sunday, the Boston Police Department, in conjunction with the Department of Homeland Security, the US Army Armament Research, Development, and Engineering Center and Fenway Park will practice and prepare for an active shooter situation.

The exercise, which will run from 7 a.m. until 1 p.m. Sunday, will include inaudible, simulated explosions and multiple rounds of realistic-sounding, simulated gunshots. During the drill various security technologies will be tested, including working dogs, metal detection and unmanned aerial systems.

"Fan safety is a topic we continually discuss and evaluate, and by participating in this exercise, led by Boston Police alongside state and federal agencies, we hope to gain valuable insight that may help enhance how we keep visitors safe at Fenway Park," said Red Sox Director of Security and Emergency Services Charlie Cellucci.

Officials said there are no threats or any security concerns, and the event is just a drill.

Boston police will put out a casting call for more than 100 volunteers to act as fans.
