"It is going to be signed in the next couple of days," Rosenhaus said.
The deal includes a $1 million base salary, a $1 million signing bonus and a $1 million incentive-based bonus based on playing time that Rosenhaus said should be easily attained.
"I am healthy and look forward to playing in 2008, but will always consider myself a Miami Dolphin," Thomas said then.
"It was a huge factor, a gigantic factor," Rosenhaus said. "At the end, it was the difference. It's a great opportunity for him."
Thomas is a native of Pampa, Texas, and then went to Texas Tech. The Dolphins selected Thomas 154th overall out of Tech in 1996. The 5-foot-11 linebacker then led Miami in tackles 10 times and is the team's career leader in that category with 1,642. His 168 games in Miami are the most by a defensive player.
After missing only 13 games in his first 11 years, and having a career-best 165 tackles in 2006, Thomas missed 11 games last season. He still had 52 tackles in the five games he played.
Thomas missed two games in September because of a concussion. Then after Miami's loss to New England on Oct. 21, his vehicle was rear-ended on Florida's Turnpike. He didn't play again and was placed on injured reserve against his wishes in December because of nagging migraines, an aftereffect of the car crash.
