Mills is a veteran of five NFL seasons and has played with New England (2006), Minnesota (2007-09), Philadelphia (2010) and Cincinnati (2010).

He was waived by the Patriots at the end of training camp in 2007 and was claimed off waivers by Minnesota. After two seasons seeing limited action for the Vikings in 2007 and 2008, he split the 2009 season between the Minnesota active roster and practice squad but did not see any game action.
