Osi apologizes for leaving Giants' practice

Update: Osi Umenyiora issued an apology for leaving practice:

“I made a mistake by leaving the facility today. I was wrong. I came in here this afternoon and met with coach Coughlin, coach Sheridan and coach Waufle and apologized and explained why I left the building; that will remain between us. I have no problem with our defensive coordinator Bill Sheridan or any of our coaches. That’s the end of it, as far as I am concerned.”

From earlier:

For those of you who think the Eagles are unique in dealing with change and controversy this offseason, think again.

The Giants are providing them with plenty of company.

Both teams are mentioned frequently by experts as favorites in the division and potential Super Bowl representatives out of the NFC.

But neither is having a particularly smooth offseason as Week 1 rapidly approaches.

Defensive end Osi Umenyiora left Giants practice Monday. For a short time this afternoon, the reason why was unknown. The Giants' scribes told us that Tom Coughlin categorized it as an unexcused absence, but that was the extent of the story.

However, Mike Garafolo of the Newark Star-Ledger is now reporting that Umenyiora's frustrations with defensive coordinator Bill Sheridan led to his departure.

Per Garafolo, Umenyiora left after Sheridan pointed out a mistake he made in Saturday's game against the Jets. Umenyiora did not confront Sheridan, but left the Giants' facility without telling the team.

The Giants and Eagles both have new defensive coordinators this season. Sheridan fills in for Steve Spagnuolo, who is now the head coach of the St. Louis Rams.

And Sean McDermott has been handed the reigns to the Eagles' defense after Jim Johnson passed away.
