The Carolina Panthers have signed Thomas Davis to a one-year contract extension, which will keep him with the franchise through 2018.

The deal is worth $6.75 million with $2 million guaranteed in 2017 and $3 million guaranteed total, according to a league source.

Davis said he had a deal in the works before team owner Jerry Richardson fired general manager Dave Gettleman and hired Marty Hurney as the interim general manager.
