According to the team's website, this will be the first time the Ravens wear their alternate jersey this season. Because the decision does not have to be approved by by the NFL, the team has the option to go with the black on white or the all black look.
Teams are allowed to wear their alternate uniform twice a year, but not during the playoffs. The Ravens have worn black jerseys twice a year for the past three seasons.
Aditionally, the Baltimore team will wear pink gloves, shoes and wristbands to raise breast cancer awareness.
The defending Super Bowl champions are 10-3 all-time while wearing the black jerseys and 7-1 under coach John Harbaugh, who joined the team in 2008.
The team has not announced when they'll use the jerseys for a second time this season.
