The Patriots have signed free agent running back Rex Burkhead. Burkhead, 26, comes from Cincinnati, where he has spent all four years of his NFL career since being drafted in the sixth round out of Nebraska in 2013. Burkhead is expected to be used primarily on special teams for the Patriots and could be a replacement for Brandon Bolden, who is an unrestricted free agent.
