The Patriots have agreed to a two-year contract extension with linebacker Gary Guyton. "We're absolutely thrilled that the Patriots have done this for him," agent Richard Kopelman told the Boston Herald. "... We had some discussions with them a while back. 'Hey, if you could, it'd be great if you could step up and do a little something for Gary this year.' And they told us they would. They were true to their word, which was fantastic." Guyton was scheduled to earn the minimum of $470,000 next season.

Reed, a second-round draft pick out of LSU in 2002, has 311 career catches for 3,575 yards and 10 touchdowns in eight seasons with the Bills. "We are excited to have Josh join us," Chargers general manager A.J. Smith said in a statement. "He was a consistent performer in Buffalo for many years. With his experience, he will be a solid compliment to our receiving corps."

The Bills have agreed to a deal with free-agent linebacker Reggie Torbor. Torbor, a six-year veteran, comes to a team looking for players familiar with the 3-4 defense they are introducing.
