Super Bowl history: 49ers, Ravens are both undefeated all-time

Someone -- either the San Francisco 49ers or the Baltimore Ravens -- is going to experience unfamiliarity at the end of Sunday.

Neither team has ever lost a Super Bowl. The Ravens are 1-0, with their only victory coming in 2001 against the New York Giants. The 49ers, meanwhile, are an impressive 5-0. Their last win came against the San Diego Chargers in 1995 in Super Bowl XXIX.

Today's Ravens still have some ties to the team's first Super Bowl. The MVP of Super Bowl XXXV was linebacker Ray Lewis, who is set to retire at the conclusion of Sunday's game. The rest of that team, though, doesn't look familiar. Trent Dilfer was the quarterback, while Jamal Lewis was the team's leading rusher. Brandon Stokley, Qadry Ismail, Ben Coates and Shannon Sharpe were a few of the receivers catching passes from Dilfer.

The Ravens beat the Giants in a blowout, 34-7. Dilfer threw for 153 yards and a touchdown, and Jamal Lewis had a touchdown and 101 yards on 27 carries.

To put the 49ers' trip to Super Bowl XXIX in perspective, Steve Young was the MVP in a 49-26 win over the Chargers. Young threw for 325 yards and six touchdowns in the win -- three caught by Jerry Rice -- blowing the Stan Humphries-led Chargers out of the water.

The 49ers won four NFL titles before Young's turn to lead the team, capturing Super Bowls XXIV, XXIII, XIX and XVI.

Super Bowl XLVII is Sunday at 6:30 p.m. ET in New Orleans.
