The Panthers' offensive line struggled to contain the Broncos' pass rush, allowing a season-high seven sacks, and Rivera said there could be lineup changes coming.
"We're going to look at different things we can do with personnel," Rivera said.
One of the players waiting for his first opportunity of the season is tackle Bruce Campbell. Acquired in an offseason trade with Oakland, Campbell played guard during his first two season with the Raiders, but Rivera said he is best suited playing behind Jordan Gross at left tackle.
"Bruce, really his best, most natural position is left tackle," Rivera said. "But we most certainly are going to look at different options."
The left tackle spot has been manned by Gross for the better part of nine seasons, and Rivera praised the work of the team captain.
"Jordan is playing very well," Rivera said. "A lot of that was an avalanche with what happened (on Sunday). He did miss a couple plays, but for the most part, when you watch him and see what he's meant to anchoring that offensive line, it's pretty solid."
About damn time we try and give Cam better protection. Hopefully Jeremy Bridges will step in and help immediately. However, it's so hard to improve an O-Line with truly no good options out there.
