The Jacksonville Jaguars have signed Telvin Smith to a four-year extension worth as much as $50 million.

Smith was in the final season of his rookie contract. He signed a four-year deal worth $2.43 million with only $211,052 guaranteed after the Jaguars drafted him in the fifth round in 2014.

Smith leads the Jaguars in tackles this season and also has two interceptions, a forced fumble and a fumble recovery.

"Telvin has been a productive player and an important part of our defense, and he has earned this second contract," Tom Coughlin, the Jaguars' executive vice president of football operations, said in a news release. "We want to identify the players who will contribute to help this team win going forward and reward those who can do that. Telvin is certainly one of those players for us."
