"I want to thank all of the Detroit Lion fans for sticking with me through this process," Tulloch said through his Twitter account. "This is a special team and I'm glad to be apart of it."
Tulloch was the biggest remaining priority for the Lions after re-signing receiver
The Lions now have 21 of their 22 starters back from last year's 10-win playoff team. The only starter not returning is cornerback
Tulloch, 27, led the Lions with 111 tackles and added three sacks and two interceptions in 16 starts. He has never missed a game in six NFL seasons.
"We've had very productive conversations with Stephen over the last couple days. We're very hopeful we can reach an agreement with him sometime soon and we're going to continue to pursue Stephen and try to get him signed,” Lions general manager Martin Mayhew said at a town hall meeting last night.
Financial terms were not disclosed, but Tulloch had reportedly been seeking a deal similar to the five-year, $42.5 million contract that D'Qwell Jackson received from the Browns.
Tulloch signed a one-year, $3.25 million contract with the Lions last July.
A fourth-round pick by the Titans out of North Carolina State in 2006, Tulloch became a full-time starter in 2008 and has 568 tackles, 7.5 sacks and four interceptions in 96 career games.
