FOXBOROUGH, Mass. (AP) -- The NFL says it is still investigating how the New England Patriots used underinflated balls in their last game but has no conclusions yet and no timetable for resolving the cheating accusations with the Super Bowl nine days away.

 

The league said Friday that evidence shows the Patriots used underinflated footballs during the first half of the AFC championship game Sunday night against the Indianapolis Colts.

It issued a statement that the Patriots have pledged full cooperation and have given the league information it requested and made personnel available upon request. Quarterback Tom Brady said Thursday afternoon he had not been contacted at that point.

The NFL said it began its investigation Sunday night and expects full cooperation from other clubs. It has hired an investigatory company to help in reviewing electronic and video information.
