Oakland Raiders LB Khalil Mack will have to wait until 2018 for a contract extension because of the extensions for QB Derek Carr and OG Gabe Jackson, according to sources.

Oakland Raiders OG Gabe Jackson has agreed to terms on a five-year, $56-million extension through 2022 Thursday, June 29, according to a source.

Cleveland Browns WR Corey Coleman (hamstring) is currently recovering from a strained hamstring — a problem that has plagued him back to his collegiate days at Baylor. Browns wide receivers coach Al Saunders said he is disappointed for Coleman since he cannot continue his on-field growth, but Saunders added he expects Coleman to return for training camp July 26, if he can improve the strength of the hamstring.

Footballguys View: Coleman had injury issues in his first year, and this particular one has been a long-standing issue. Every time he misses an OTA, camp day or anything else he is stymieing his development. Coleman has the ability but that won’t make a difference if he can’t stay on the field and off the trainer’s table. The uncertainty at quarterback doesn’t help his value either. In early drafts he is currently the 41st receiver off the boards, with an overall ADP of 106.

Miami Dolphins C Mike Pouncey (hip) is expected to be ready for the season, barring a setback, according to a source close to him.

Footballguys View: The Dolphins need Pouncey 100 percent healthy this season. Whenever he was not in the lineup, the blocking was not there consistently. With Laremy Tunsil shifting to left tackle, Pouncey is going to have to be the strong presence in the middle of the line.

Free-agent LB Zach Orr (neck) has been told by doctors that the strength of the tendons and ligaments should protect his C1 vertebra, which is only 80 percent formed. He has received the green light to play, but he’ll have to manage his congenital neck issue.

Carolina Panthers QB Cam Newton’s down year in 2016 was due in part to a loss of confidence in his offensive line, which was hit hard by injuries. A big part of Newton’s game has always been his ability to hold the ball, buy time and strike downfield. The injuries to the line affected that.
