The 10-year veteran signed a three-year, $2.48 million contract with a $150,000 signing bonus, according to the Charlotte Observer. He fills the void created by the loss of Mark Fields, who has been diagnosed with Hodgkin's disease.
"I really like the commitment at Carolina," Caldwell, 32, told the Charlotte Observer. "They're an up-and-coming team with a blitzing and attacking style. I talked to a lot of people about them and it seemed like a good opportunity for me, a chance to get on the field."
In 10 years with five different teams, Caldwell has played in 149 games with 49 starts. He has recorded 672 tackles, 14 ½ sacks, eight interceptions, five forced fumbles, and two fumble recoveries.
He was a third-round pick by Cleveland in the 1993 draft, and also has played for Arizona, Baltimore, and Philadelphia.
