(CBS) – The Chicago Bears take to the field this Sunday for their season opener at Soldier Field.

Action behind the scenes was well underway Friday.

CBS 2’s Roseanne Tellez reports.

It looks pretty empty. No team. No fans. But there’s actually a small army of technical types from CBS Sports inside, preparing for a broadcast that will be viewed by more than a million and a half people.

After of a summer of concerts and soccer, it’s back to football.

The field is getting water; the grass, some new seed, and cleaning people are making sure Solider Field is spic and span for the Chicago Bears’ home opener.

In the underbelly of the stadium, it’s all about production.

CBS Sports rolled into town with trailers filled with equipment that needs to be put in place by game time.

And a state-of-the-art facility like Soldier Field means a lot of equipment. Pete Kallander is the technical manager.

“There are probably 30 different camera positions here. In an old stadium, you might find a dozen. So, it really affects the on-air product,” he says.

There’s equipment to move, cables to run and some 80 crewmembers hoping to bring their A-game to Sunday’s broadcast.

Phil Simms and Jim Nantz will take to the booth for Sunday to bring you all the action.

It takes about three days to set up for a broadcast like this, and only three hours to tear it down.

Hopefully, you’ll still be celebrating a Bears victory when CBS Sports rolls out of town.
