A league source tells us that the Carolina Panthers have reached an agreement with linebacker Dan Connor.

Connor, an insider linebacker from Penn State, was a third-round pick in the 2008 draft.

It’s a four-year deal, with a $789,000 signing bonus and minimum base salaries.  The fourth-year salary increases to $1.2 million or the low restricted free agency tender, whichever is greater, based on a minimum playing-time trigger.

At Penn State, Connor set the career tackling record with 419, shattering the prior record of 372, which had been owned for a year by Paul Posluszny.
