Ben McAdoo confirmed on Sunday night that the New York Giants had some concerns about the air level of footballs in Pittsburgh on December 4.

"I don't really know anything about it," McAdoo said. "I just know that they said that they felt a little. ... I don't know, the PSIs were a little low, so they checked them, and they just let me know they checked them."

Jay Glazer on FOX originally reported the concern.
