Panthers training camp 2018: Panthers release Drew Iddings; are looking to add a tight end to the roster Update: According to Max Henson Youth Greg Van Roten Jersey , the Panthers have signed undrafted rookie tight end Cam Serigne to fill the roster spot left by Iddings.According to a tweet from Bryan Strickland, the Carolina Panthers have released defensive lineman Drew Iddings on the eve of training camp and are expected to fill his roster spot with a tight end due to Chris Manhertz starting the season on the Physically Unable to Perform (aka PUP) list.With Manhertz being unable to suit up at the start of training camp it makes a little sense to want an extra tight end running drills with the offense. The Panthers currently have four active tight ends on the roster: Greg Olsen, Ian Thomas, Evan Bayliss and James Vander Laan. Given that they’ll want to limit Olsen’s activities as much as they can over the first few days (since he’s kind of an important piece to the offense being good), adding someone to get Manhertz’s reps in practice is probably a solid decision.The Panthers will hold their first training camp practice at Wofford College in Spartanburg Stitched Greg Van Roten Jersey , SC tomorrow at 6:30 p.m. ET.Stay tuned for more information on this story, as we’ll provide an update to the player that is added to the roster to replace Iddings as soon as that information is made available to us.Matt Kalil placed on injured reserve The Carolina Panthers have placed left tackle Matt Kalil on injured reserve. He had a lingering injury to his right knee during training camp. The team had to wait until this afternoon to place him on IR so that he would be eligible to return to the team if his knee does recover. Players placed on the list prior to final roster cuts, like right tackle Jeremiah Sirles, cannot be returned to the active roster for the duration of the season. Kalil will be eligible to return after missing eight games. For the Panthers, that means their Thursday night match up with the Pittsburgh Steelers.The Panthers have signed cornerback Lorenzo Doss — who miraculously cleared waivers today after being released yesterday — to fill the empty roster spot. Doss is a 4th year veteran in the NFL Youth Eric Reid Jersey , however, at 5’11” and 185 pounds, he lacks the ideal size to play any offensive line position. He will likely remain in the defensive backfield. Instead, the Panthers will look to some combination of Taylor Moton and Amini Silatolu, who is also coming back from a knee injury Stitched Eric Reid Jersey , to fill in on Cam Newton’s blindside. The good news today is that right tackle Daryl Williams and Silatolu are on track to be back on the field earlier than anticipated. With any luck, this news may just be one step back and two steps forward for the battered Panthers offensive line group.
