The biggest injury in Super Bowl XLVII may have allowed the San Francisco 49ers to continue one of the biggest comebacks in title game history.

Baltimore Ravens defensive lineman Haloti Ngata, who specializes in stopping the run, suffered a sprained knee on Frank Gore’s 6-yard touchdown run when he had his legs rolled under him in the third quarter, according to NFL.com.

Ngata grabbed his knee as he collapsed to the turf, where he stayed down for several minutes. Accompanied by trainers, Ngata was taken to the locker room.

Also, Ravens running back Berard Pierce suffered a knee injury, according to the Baltimore Sun, but he returned.

Pierce was favoring his knee, limping noticeably as he was helped by trainers.

The third-round draft pick from Temple has been bothered by a bone bruise in his right knee throughout the playoffs.

And defensive back Ed Reed left in the first quarter with a knee injury after colliding with 49ers tight end Vernon Davis, but the Bleacher Report said Reed returned later in the first half.

No San Francisco 49ers suffered any significant injuries.
