John Harbaugh has said that he will be focusing on the teams ahead of the Super Bowl rather than his rivalry with his brother.
The Ravens head coach told reporters: "We'll try to stay out of that business, we'll let the two teams duke it out as much as possible. Let's just cut that right out. Let's move past that and let's talk about the two teams.
"[The 49ers] have a great staff. They're physical players, man. They run the ball, they throw the ball, they have a quarterback that's throwing the ball all over the place. They've got a rough-house defense. There's a reason they are in the Super Bowl. Love the way they play.
"I don't know if we had a dream this big. We had a few dreams, a few fights. We had a few arguments. Just like all brothers."
The two sides last played each other in the 2011 regular season, with the Ravens taking the victory.
