When the Carolina Panthers drafted David Gettis in 2010 and Brandon Hogan in 2011, the organization believed those two players could compete for the No. 2 wide receiver and No. 2 cornerback positions, respectively.

After both spent time on the inactive list last season and hardly saw the practice field this offseason, Gettis and Hogan will now be sidelined early on.

On Monday, Gettis was placed on the physically unable to perform (PUP) list while Hogan was put on the injured reserve as the Panthers reduced their roster to 75 players in the first round of preseason cuts.

Being placed on PUP means Gettis will have to sit for six weeks. He’ll be eligible to return after the Panthers’ bye week against the Cowboys on Oct. 21.

“We’re very happy right now with the production the wide receiver group has given us and the competition there,” Panthers general manager Marty Hurney said. “That enables us to get Davis another seven weeks or so to get more confident in the knee and get the hamstring (to) 100 percent and be fully ready to go.”

The Panthers took a chance on Hogan in the 2011 draft after he tore his left ACL in the final regular season game of his college career.

Hogan sat out the first eight games of the season on PUP before returning in the final three games of the year. But after two practices in Spartanburg, his knee began swelling. He couldn’t go on PUP because he had practiced already. He had arthroscopic surgery on his left knee Friday.

“They told me that they’re not trying to wash their hands of him,” said Drew Pittman, Hogan’s agent. “They’d like to try to find a way to keep him in the fold. It’s just that the rules are kind of working against us right now.”

OTHER CUTS: The Panthers cut four receivers Monday, none of whom recorded any receiving stats in the first three preseason games.

Darvin Adams, Michael Avila, Brenton Bersin and Rico Wallace were all released. The four had mostly seen time on special teams, or with the third-string offense. Carolina, deep with listed tight ends, cut tight end Greg Smith, too.

Guards Roger Allen, who had not played in an NFL game since his rookie season in 2009, and Will Blackwell were also released as the Panthers solidified one of the best offensive lines in the league.

Carolina also cleaned up its backfield by releasing Lyndon Rowells and Josh Vaughan, leaving Tauren Poole and Armond Smith to compete for the third running back spot behind DeAngelo Williams and Jonathan Stewart.

The other side of the ball is more unclear. The Panthers are still testing out their depth on the defensive line, and their only cut on the defensive side of the ball was defensive end Eric Norwood.

Said Hurney: “We felt like we’ve got depth there. Sometimes with guys who have been there, if you give them a chance when you know they’re not going to make it, if you can increase their chances of getting on somewhere else (by cutting them), you feel like it’s the right thing to do.”

STEWART, SMITH UPDATE: Stewart and wide receiver Steve Smith are both day-to-day, Hurney said.

Stewart sprained his ankle late in the second quarter against the New York Jets on Sunday night. He was carted off the field after hobbling to the sideline, and x-rays after the game were negative. Head coach Ron Rivera said after the game Stewart will not play Thursday against the Pittsburgh Steelers

Smith did not make the trip north with the team, instead staying home to nurse a foot infection that has sidelined him for a week. He will likely not participate Thursday, as well.
