Kansas City, Mo. ? The Kansas City Chiefs continued to shore up their leaky defense, signing Miami safety Sammy Knight to a five-year contract, Chiefs president Carl Peterson said. No terms of the deal were released Friday.

Knight, 29, was a Pro Bowl safety in 2001 with the New Orleans Saints and a starter for the Dolphins the last two seasons. The Chiefs signed linebacker Kendrell Bell to a seven-year contract Tuesday.

“We went into free agency wanting to acquire a linebacker, safety and a corner,” Peterson said. “We have two of those positions right now.”

Knight, 6-foot, 215 pounds, has 35 interceptions, with four returned for touchdowns, and nine forced fumbles since signing with the Saints in 1997. He has played in 126 games, including a streak of 108 consecutive games.

His 35 interceptions are the second-highest total in the league during the past eight seasons.

Knight has played both strong and free safety and has six consecutive seasons with more than 100 tackles, including 127 for the Dolphins last season.

The Chiefs have finished near the bottom of the league in most key defensive categories each of the past three seasons. While going 7-9 last season, Kansas City finished 32nd in pass defense and 31st overall.
