Osi Umenyiora acknowledged Tuesday that he had a minor tiff with his new defensive coordinator, but he said his decision to skip practice probably was the worst thing he has done in his six-year NFL career. Umenyiora declined to disclose the nature of his disagreement with defensive coordinator Bill Sheridan, saying only the issue that set him off was "minuscule" and never should have escalated. The Giants fined Umenyiora an undisclosed amount of money that the player said would feed a lot of people in undeveloped countries. "Do I regret it? Absolutely," Umenyiora said after practice Tuesday. "It was a very, very bad moral decision on my part and an even worse financial decision on my part. So everything is cool now. I talked to who I needed to talk to and apologized to those I had to apologize to. It was so stupid and trivial for me to do that. Sometimes when you get emotional, things happen like that."
