The Miami Dolphins signed former Detroit Lions safety Louis Delmas to a one-year contract worth up to $3.5 million
They also cut cornerback Dimitri Patterson to save $5 million against the salary cap.
Patterson finished last season on injured reserve with a groin injury.
Delmas, 26, was cut by the Lions. He has had knee problems that caused him not to practice frequently last season. He was due a $6.5 million salary-cap figure prior to being released.
For his career, Delmas has 328 tackles, six interceptions, five sacks and four fumble recoveries.
"He is leader on and off the field and has a proven track record of playmaking that will benefit the entire defensive unit," Dolphins general manager Dennis Hickey said.
