The Washington Redskins announced that they will be breaking ground for an indoor practice facility at Redskins Park.

Head coach Mike Shanahan said late last season that the team would be building a heated field and an indoor facility so players could practice during inclement weather.

That came after Washington was forced to practice offsite four times during the 2010 season.

In a news release issued by the team Thursday evening before its game against Tampa Bay, General Manager Bruce Allen made the news official.

Described as an “air structure,” the facility will be built over a full-size football field and is expected to be completed later this fall.

“Our new state-of-the-art facility will help our team prepare for games and will allow the Washington Redskins Charitable Foundation to hold special events,” Allen said. “Although we embrace playing all of our games outdoors, our new facility will ensure that our game preparation will not be disrupted due to inclement weather.”

A team spokesman said construction of the practice bubble in Ashburn has no bearing on whether the Redskins would move to Prince George's County. No decision has been made on that matter.
