Carolina Panthers linebacker Thomas Davis’ deal has been restructured to free up $3.8 million in salary-cap space a league sources said according to Pat Yasinskas of ESPN.com. The Panthers chose not to exercise an $8 million option bonus that was due this week. The bonus was put in as a safeguard when Davis signed a new contract last summer and he suffered his third injury early last season. Davis’ cap figure for 2012 is now a comfortable $2.1 million. In addition to not getting the bonus, Davis took a cut in base salary from $2.25 million to $700,000 for this season. Source: The Redzone
