Last week, the Giants sent a complaint to the NFL in which they claimed the Steelers in their Week 13 victory over New York played with deflated footballs. The league quickly closed the case, saying proper protocol was followed.
This week, the Giants are under investigation by the league after the Cowboys filed a complaint claiming New York illegally used walkie-talkies when its headsets weren't working during Sunday night's 10-7 victory over Dallas, according to the New York Post.
Per the report, the radio transmission went down briefly early in the game but the issue was quickly resolved.
