The Panthers want to keep their highly-paid, backfield tandem intact.

Despite being about $10 million over the projected $122 million salary cap, the Panthers hope to keep both running backs DeAngelo Williams and Jonathan Stewart, according to a league source with knowledge of the situation.

Williams, 29, is due to make $5 million this year and a has a cap figure of $8.2 million.

The team believes it can retain Williams at his current numbers. But a restructuring is possible depending on the team's other moves prior to the March 12 start of the league year, the source said.

When the Panthers signed Stewart to a five-year, $36.5 million extension last August, there was speculation Carolina would not be able to afford both backs. Green Bay was among the teams who inquired about Williams before the trade deadline, but he remained in Charlotte and re-claimed his starting spot after Stewart went down with ankle issues.

Williams, the franchise rushing leader, rushed for 737 yards and five touchdowns last season. He ran for a club-record 210 yards in a Week 17 win at New Orleans.
