Middle linebacker Sean Lee and the Dallas Cowboys have agreed on a six-year contract extension through the 2019 season.
A story on the team's website Wednesday night said Lee's deal is worth about $42 million but could escalate as high as $51 million depending on different incentives.
Lee's agent, Mike McCartney, posted a message on his Twitter account Wednesday congratulating Lee for ''agreeing to a 6 year extension with the (at)dallascowboys''
Lee is going into his fourth NFL season since being a second-round pick from Penn State in 2010.
During his rookie season, Lee played 14 games behind Bradie James and Keith Brooking. He became a full-time starter in 2011, but missed 10 games last season after ligament damage in his right big toe.
