IRVING, Texas (AP) -- Dallas Cowboys middle linebacker Sean Lee signed a six-year contract extension Wednesday, a deal that goes 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. The guaranteed money is around $16 million.
"I'm extremely excited. I was blessed to be able to be drafted by a great franchise," Lee said in a video interview posted along with the story. "To have an opportunity to be here a long time and hopefully compete for a Super Bowl is fantastic."
Lee's agent, Mike McCartney, posted a message on his Twitter account congratulating the linebacker.
"Congrats to SEAN LEE for agreeing to a 6 year extension with the @dallascowboys", the agent tweeted Wednesday.
Lee is going into his fourth NFL season since being a second-round pick from Penn State in 2010.
The high-energy linebacker is a key part for the Cowboys in their switch to a 4-3 system under new defensive coordinator Monte Kiffin.
Lee played only six games last season, when he had 77 tackles before being sidelined by a torn ligament in his right big toe.
During his rookie season, Lee played 14 games behind Bradie James and Keith Brooking.
He became a full-time starter in 2011 and led the team with 131 tackles, 52 more than any other player, despite playing the second half of the season with a broken left wrist protected by a bulky cast and missing a game because of the injury.
Without being specific, Lee said his new contract takes injuries into account.
"I've said I need to find a way to stay on this field, and the contract is extremely fair, where if I'm on the field the whole year I'll be able to get paid," he said.
"At the same point, if I do have injuries, it protects the Cowboys, and I think that's fantastic, especially with the injuries I've dealt with in the past."
Lee said his goal is to be on the field every game.
He was also hampered by injuries during his rookie camp and early in his first season, though he played 14 games without starting.
There was also a December 2010 game at Indianapolis where Lee intercepted Peyton Manning twice. He returned one for a touchdown and set up a game-winning field goal in overtime with the other.
After signing the deal Wednesday night, Lee said he was already focused on practice the next day. The Cowboys have two preseason games remaining, including Saturday night at home against Cincinnati, before the Sept. 8 opener at home against the New York Giants.
"It's great to have it done," he said. "Being able to focus on this year, focus on winning, focus on me becoming a better football player and staying on the field, making sure I'm healthy so I can help this team win."
