As the Ravens prepare to return to New Orleans on Monday night, site of their Super Bowl XLVII victory over the San Francisco 49ers, they're practicing indoors this week.
The Ravens' indoor practice facility shields them from the cold temperatures outside this week, and it also simulates the conditions at the Mercedes-Benz Superdome, where they'll play the New Orleans Saints. The Ravens also will incorporate loud noise at the practice field.
"We're going to be playing indoors, and it's going to be loud," Ravens coach John Harbaugh said. "This helps us."
The Ravens have played one indoor game this seson, a 20-13 loss to the Indianapolis Colts. Last season, they beat the Detroit Lions at Ford Field.
"The domes are always loud, but all the stadiums seem like they're loud," Harbaugh said. "We've been in all the domes pretty much lately. We were in Detroit last year, Indy this year. Communication on offense is something that we're emphasizing this week. You heard it in here.
"We had crowd noise in here with the music. It was very loud. And it's a big emphasis for our guys to communicate, make sure we're on the same page and get assignments right. We don't want to not move the ball because we're not blocking the right guy or not carrying out the right route or whatever. That's really important for us."
