NFL-National Football League roundup

Aug 29 (The Sports Xchange) - Washington Redskins Pro Bowl left tackle Trent Williams agreed to a five-year, $66 million contract extension, according to multiple reports Saturday. The deal makes Williams the highest-paid offensive tackle in NFL history. Williams will receive $43.25 million in guarantees and $32 million at signing, and will average $13.2 million per year. Williams, 27, confirmed the extension on Twitter: "Happy to announce I will be a Redskin for the next 5 years. This is a dream come true HTTR 4 Life." Williams just completed his fourth season as an offensive captain for the Redskins and has been among the league's top left tackles since he was selected fourth overall in the 2010 NFL Draft. Williams battled through multiple injuries to play in and start 15 games in 2014. - - Just hours before an independent neurologist announced Robert Griffin III was not cleared from a concussion, Redskins head coach Jay Gruden said the quarterback had been given final medical clearance from multiple doctors to play in Saturday night's preseason game. "He is cleared from all the doctors, the neurologist he has been cleared," Gruden said Friday afternoon in an interview taped with NFL Network before the news broke. A few hours later neurologist Dr. Robert Kurtzke said he wants Griffin to be retested before returning to the field from a concussion, casting doubt into his availability for the season opener in two weeks. Griffin suffered concussion-like symptoms in an Aug. 20 preseason game against the Detroit Lions, but practiced all week and was initially cleared by Dr. Kurtzke. - - The Houston Texans officially released veteran safety Stevie Brown. Brown spent the last three seasons with the New York Giants, and the New York Daily news reported a team source said the Giants are hoping to bring in the 28-year-old for a workout. - - Jacksonville Jaguars tight end Julius Thomas is reportedly making good progress during his recovery from a hand injury and could be ready to play in the regular-season opener against the Carolina Panthers on Sept. 13. - - The Arizona Cardinals released safety Ross Weaver. The 6-1, 206-pound Weaver signed with the Cardinals on Aug. 11. He spent the last 11 weeks of the 2014 season on the Cardinals' practice squad and remained with the team this offseason until being released on May 11. - - New York Jets center Nick Mangold is being credited for helping end a crime spree in his neighborhood. Mangold heard his car alarm go off while at his home in Chatham, N.J., last Sunday morning. He called 911 at 5:30 a.m. when he spotted burglars and noticed his garage door open, according to police. A short time later, police stopped a vehicle in the area and took five suspects into custody. (Editing by Andrew Both)
