BOSTON (CBS) — The Patriots have spent the first few days of free agency acquiring players from outside of the organization, but on Friday afternoon, they re-signed one of their own.

The Patriots have agreed to a four-year contract with cornerback Kyle Arrington. The news was first reported by Jeff Howe of the Boston Herald and Mike Reiss of ESPN Boston.

Shortly after news broke on Twitter, Arrington took to Twitter himself to react.

Thankful and Blessed for another opportunity. Extremely grateful for all the support from the New England community and beyond. #Patsnation—

Arrington, who will turn 27 in August, joined the Patriots in 2009. He has averaged 78 tackles per season over the last three years, recording seven interceptions in 2011 and leading the league. However, he followed that up with zero picks in 2012.

In 2010, he scored a touchdown on an interception return against Green Bay. He also scored a touchdown in Miami on a blocked field goal return.
