He sustained a herniated disk in his neck during a 24-19 win over the New York Giants on Dec. 22. -- The Carolina Panthers signed veteran linebacker Thomas Davis to a one-year contract extension, the team announced. The deal for Davis, a first-round draft pick of the Panthers in 2006, runs through the 2018 season.
