NFL-National Football League roundup

July 25 (The Sports Xchange) - Cleveland Browns quarterback Johnny Manziel worked on his mechanics with Super Bowl-winning coach Jon Gruden as a tutor just days before training camp gets started this coming week. Manziel, in his second NFL season, spent part of the past week working with the former Tampa Bay Buccaneers and Oakland Raiders head coach in Tampa, Fla., concentrating on film study and throwing mechanics, according to WalterFootball.com. Manziel won the Heisman Trophy at Texas A&M in 2012 and was Cleveland's first-round draft pick last year, but his off-field behavior led to criticism. He has taken steps to clean up his life, spending 10 weeks in a rehab center earlier this year. Josh McCown, 35, opens camp as the firm starter. --- Arizona Cardinals rookie wide receiver Damond Powell was shot outside his home in Toledo, Ohio. Powell was wounded Friday night when he was shot in the face, but police said his injures do not appear to be life-threatening. According to the Toledo Police Department, the 22-year-old Powell was shot around 8:36 p.m. while sitting in a car with some friends in the driveway of his home. Powell was signed as a free agent on May 5 after two years at the University of Iowa. "We are aware that Damond Powell was the victim of a shooting last night in Toledo, where he remains hospitalized," the Cardinals said in a statement. "We have been in communication with his family to offer whatever support and resources we can provide." --- The Pittsburgh Steelers signed general manager Kevin Colbert to a two-year contract extension Saturday that will keep him with the team through the 2018 NFL Draft. Colbert's deal comes two days after the Steelers reached a two-year extension with head coach Mike Tomlin that goes through the 2018 season. The 58-year-old Colbert is entering his 16th season with the Steelers and fifth year as the team's general manager. --- The Indianapolis Colts agreed to contract terms with cornerback D'Joun Smith and defensive end Henry Anderson. Smith was selected by the Colts in the third round of the 2015 NFL Draft. He played in 44 games, including 34 starts, at Florida Atlantic and had 120 tackles, 29 passes defensed, three forced fumbles, two fumble recoveries and nine interceptions. Anderson was also picked by the Colts in the third round of this year's draft. He played in 48 games, including 35 starts, at Stanford and finished with 140 tackles, 17 sacks, one forced fumble, one fumble recovery and seven passes defensed. --- The Cardinals and tight end Jermaine Gresham agreed to terms on a one-year contract. The two-time Pro Bowl tight end underwent surgery to repair a herniated disk in his back in March, ruining any chance he had at receiving a lucrative contract this year. The condition was discovered during a free-agency visit. Gresham spent his first five years with the Cincinnati Bengals, who drafted him in the first round in 2010. He caught 280 passes for 2,722 yards and 24 touchdowns for the Bengals. (Editing by Larry Fine) ))
