Not the greatest day to be a veteran offensive lineman for the New York Giants. On the first day of post-lockout NFL business, the Giants have informed longtime center Shaun O'Hara and guard Rich Seubert that they will be released. The Giants have work to do to get under the salary cap, and they appear to have begun that work by ridding themselves of the contract of a couple of injured veterans on the interior of their offensive line.

The Giants, who are about $6 million over the cap, will save about $5.3 million with those two cuts. How they replace their starting center of the past seven years and one of the guys who filled in for him when he was injured last year remains to be seen. Backup center Adam Koets is coming off knee surgery himself.

There has been some talk of left tackle David Diehl moving inside, but that assumes Will Beatty is ready to take over the starting left tackle position. And we're still waiting to see what happens with Shawn Andrews, who filled in at a couple of different positions along the line in 2010 and could be the starting left tackle if Beatty isn't ready. Many have assumed that Andrews was at risk to be cut, since he stands to make $7.5 million this year. But if he agrees to restructure, it appears as if they have a couple of ways they could still use him.

Regardless, it appears as though they will be needing some new bodies for the offensive line in New York. Expect this, along with linebacker, to be the position they look to address in free agency.

O'Hara, incidentally, was the Giants' NFLPA player rep and, along with Giants owner John Mara, a key figure in the negotiations between players and owners. Got to think it burns him up to have sat across the table from Mara those many months only to be blindsided like this on the first day after the lockout ended. O'Hara was the Giants' starting center for every game but one from 2005-09. He missed 10 games last year with foot and ankle injuries.
