11 of the New England Patriots' 12 allotted footballs were under-inflated during Sunday's game against the Indianapolis Colts, league sources told ESPN.
"We are not commenting at this time," Greg Aiello, the NFL's senior vice president of communications, told the sports news-outlet.

An NFL letter regarding the investigation and provided to the Boston Globe confirmed similar findings about the game balls used by the Patriots in their 45-7 AFC championship victory over the Colts.
Sources familiar with the investigation told ESPN that the footballs were found to be under-inflated by two pounds of air (PSI) less than what NFL regulations require.

The New England team may have drained the air from the footballs to make them easier to handle during the windy conditions.
Troy Vincent, the league's senior executive vice president, told ProFootballTalk.com Tuesday the investigation will formally conclude in "two or three days."
