The extension is worth $36 million with $20.5 million in guaranteed money over four years, Casey's agent, Drew Rosenhaus, told ESPN's Adam Schefter.
“We are excited to come to an agreement on an extension with Jurrell,” said Titans general manager Ruston Webster. “This is something Jurrell has earned not only with his play on the field but his work ethic as well. We appreciate Jurrell’s professionalism through this process and look forward to many good years to come.”
Casey, who is considered one of the best pass-rushing defensive tackles in the league, recorded 10.5 sacks and 38 tackles in 14 games last season. The 6-foot-1, 305-pounder has compiled 16 sacks and 11 tackles in 47 games (45 starts) over three seasons.
The Titans drafted Casey, 24, out of USC in the third round of the 2011 draft. Tennessee opens the regular season Sept. 7 at Kansas City.
