(AP Photo/Jason Redmond) The Associated Press July 27, 2013 Comments OXNARD, Calif. — The Dallas Cowboys placed defensive tackle Jay Ratliff and guard Mackenzy Bernadeau on the physically unable to perform list after both suffered hamstring injuries in conditioning tests before training camp. Ratliff, Bernadeau and guard Nate Livings, a former LSU player, were sidelined for the first camp workouts Sunday. Livings was placed on the non-football injury list with a foot problem. All three are projected starters. Ratliff passed the conditioning test despite the injury. Bernadeau still has to get through the test to be cleared. Guard Ronald Leary (Southern Lab), offensive lineman Ryan Cook and deep snapper Louis-Philippe Ladouceur also were placed on the non-football injury list. The Cowboys signed offensive tackle Demetress Bell (Northwestern State) and wide receiver Lavasier Tuinei and placed them on the non-football injury list. Dallas also signed quarterback Alex Tanney. Dolphins POUNCEY MUM ON ‘FREE HERNANDEZ ’ HAT: Miami center Mike Pouncey declined to join twin brother Maurkice in apologizing for wearing a baseball cap that supported former college teammate Aaron Hernandez. The Pounceys were photographed during their recent birthday party in Miami wearing caps that read “Free Hernandez.” The former New England Patriots tight end played with the Pounceys at Florida in 2007-09. Hernandez is charged with murder in Massachusetts and has pleaded not guilty. “I’m just here to focus on football,” he said. Later he added, “We get paid a lot of money to act a certain way, and that’s the way we should be acting.” Maurkice Pouncey, an All-Pro center for the Pittsburgh Steelers, said last week on his Twitter account that he understood the seriousness of the situation and regretted making light of it. Also, Dolphins top draft pick Dion Jordan sat out the start of training camp because his surgically repaired right shoulder has not fully healed. He was placed on the non-football injury list. The defensive end/linebacker from Oregon, the No. 3 overall pick, wore uniform No. 95 but watched the first practice from the sideline. Coach Joe Philbin declined to say how long Jordan is likely to be sidelined.
