Free agent quarterback Derek Anderson could be close to signing with the Carolina Panthers as Darin Gantt of The Charlotte Observer tweets that Anderson is coming in for a workout. The Oregon State product has completed 52.6% of his pass attempts for 9,148 yards with 53 touchdowns and 55 interceptions in his five-year career with the Cleveland Browns and Arizona Cardinals. Anderson went to the Pro Bowl in 2007, but has a completion percentage under 50% of the last three seasons and has just 19 touchdowns to offset his 28 interceptions. Anderson, 28, signed a two-year, $7.25 million contract with the Cardinals last March, but was released last week as the club acquired quarterback Kevin Kolb from the Philadelphia Eagles. The three quarterbacks under contract -- Cam Newton, Jimmy Clausen, and Tony Pike -- have an average age of 23.8 years. Source: Mac's Football Blog
