CHARLOTTE, N.C. – The Carolina Panthers aren’t in the market to unload any players as the NFL trade deadline approaches on Tuesday.

But coach Ron Rivera didn’t rule out a potential purchase for general manager Dave Gettleman and his staff.

Much could depend on what happens in Sunday’s game against the Arizona Cardinals in terms of the Panthers (1-5) believing they still are in playoff contention or building for next season.

“Maybe this is the type of game that could dictate whether or not we’re buyers,’’ Rivera said. “That’s pure speculation.’’

Rivera said there are a number of players rumored to on the trade block that Gettleman and his staff have been looking at.

Most belong to the Cleveland Browns (0-7_, who are rumored to be shopping left tackle Joe Thomas, as well as cornerbacks Joe Haden and Tramon Williams.

San Francisco left tackle Joe Staley also could be available.

But all of those players likely would require giving up at least a second- or third-round pick, and Gettleman covets his draft picks. Gettleman also would have to decide, particularly at cornerback, if he’s willing to spend that kind of money.

He rescinded the franchise tag ($13.95 million) of cornerback Josh Norman and let him sign with Washington.

Haden, for example, would count only $5.347 million against the cap this season if he’s traded the week of the deadline. But the 27-year-old would count $11.2 million ($4 million guaranteed) in 2017 and $11.2 million in 2018.

The Panthers need help at cornerback, but they drafted three this year whom they want to see develop. They also could need help at left tackle if the concussion that on Sunday will have sidelined Michael Oher for four straight games is deemed to be a long-term issue.

At the same time, they like what right tackle Mike Remmers has done since replacing Oher and what Daryl Williams has done in replacing Remmers.

“We’ve got a good, solid group,’’ Rivera said. “I don’t think there is anybody we’re looking to sell. For us everything is going forward.’’
