Two pounds may not sound like a whole lot, but the NFL mandates that game-ready footballs be inflated with between 12.5 and 13.5 pounds of air. As noted by Yahoo!'s Dan Wetzel, a two-pound under-inflation means the balls were approximately 16 percent less inflated than normal.

As for the 11 footballs, according to the NFL's rulebook digest, "the home club shall have 36 balls for outdoor games and 24 for indoor games available for testing with a pressure gauge by the referee two hours prior to the starting time of the game to meet with League requirements." Pre-game testing is mandated for 12 primary footballs supplied by the home team, with 12 backups also made available.

Additionally, our Jason La Canfora is reporting that some with the Ravens suspect some of the kicking balls used in their divisional round game were deflated as well.

There appeared to be less air in some kicking balls which may have had an impact on the depth of punts and kickoffs in AFC Divisional game
