The NFL has reviewed whether New York Giants players Dan Connor and Cullen Jenkins deliberately impeded the Dallas Cowboys' no-huddle offense by faking injuries Sunday night and found no basis for punishment at this time, a league source told ESPN NFL Insider Ed Werder.

Cowboys owner Jerry Jones and quarterback Tony Romo both suggested the Giants violated the league policy, but the team did not file an official complaint.

Giants coach Tom Coughlin adamantly denied the accusation Monday, saying it was "absolutely not true."

Connor did not return to the game. The team announced he had a "burner." Jenkins did return, though the team never announced anything about his injury, even to which body part it supposedly was.

"Both of those players were injured," Coughlin insisted in a Monday conference call. "Connor never returned to the game. And Cullen was in a position where he needed to regroup. So that wasn't orchestrated at all."

Last week the league sent a memo to the 32 teams about "faking injuries," saying that a team would be subject to disciplinary action even if no penalties were called in the game.

Jones said Sunday he thought some gamesmanship was involved.

"I thought us experts on football were the only ones who could see that," Jones said, laughing and winking. "No, it was so obvious it was funny. It wasn't humorous because we really wanted the advantage, and knew we could get it if we could get the ball snapped."
