The Carolina Panthers have until March 12 to trim about $10 million in salaries, but coach Ron Rivera is staying mum on the Panthers’ plans.

However, Rivera did say the plan to reach the $121 million salary cap is taking shape.

“We’re very close with all the things we’ve got to start doing,” Rivera said after giving the keynote address and the NFL-NCAA Coaches Academy on Sunday night. New Panthers general manager Dave Gettleman “has been sitting down and talking to our guys in terms of cap. All that stuff’s being put into place right now.”

In the past month, the Panthers have restructured the contracts of Pro Bowl center Ryan Kalil and running back Jonathan Stewart. Kalil’s deal freed up about $3.45 million in cap space, but Stewart’s added about $200,000.
