Locking up Rivera does provide some stability going forward for the Panthers, who owner Jerry Richardson said he will sell after being accused of workplace misconduct this season. Financial terms were not released.
Carolina are 64-47-1 under Rivera and progressed to Super Bowl 50 at the end of the 2015 season, when they lost to the Denver Broncos.
Rivera also led Carolina to three consecutive divisional championships, the first NFC South team to accomplish even back-to-back titles.
The Carolina Panthers only lost five games in the regular season after dropping twice that many previous year.
Panthers hand Rivera extension through 2020
During a period of uncertainty in Carolina, the Panthers have made things a little more certain.
Carolina finished the 2017 season with a 11-5 record, good for a wild-card berth. Carolina's.576 winning percentage during Rivera's tenure is seventh best in the National Football League during that time. Carolina needs skill-position players, and its offensive line left Newton to pick himself up far too many times this year. Rivera already has 67 wins and with a road game in New Orleans will pass Fox with his fourth playoff appearance. Carolina is ranked seventh in defense this season.
"This is a tremendous place with tremendous support from ownership and the people that work in the organization. That's a big reason why I want to continue my association with this organization". Another milestone for Rivera to check off his list in the coming year as the Panthers most successful coach ever.
Before joining the Panthers, Rivera was an assistant coach with the San Diego Chargers (2007-10), Chicago Bears (2004-06, 1997-98) and Philadelphia Eagles (1999-2003).
