The post-September 4 roster churning continues.
A league source tells us that defensive tackle Jay Alford, a third-round pick of the Giants in 2007, has agreed to terms with the Raiders.
Alford missed all of 2009 with a knee injury suffered in the preseason. He appeared in every game of his first two seasons, with three starts in 2008.
Alford played in each of the Giants’ four preseason games in 2010.
