Tom Brady limps off the practice field The New England Patriots had a scare Wednesday when quarterback Tom Brady limped off the practice field after he was hit after throwing a pass. Coach Bill Belichick did not talk with reporters after practice and the team made no official comment. A person familiar with the injury said that an MRI exam was negative and that Brady had sprained his left knee. According to the person, Brady is day to day. Club President Jonathan Kraft told WBZ-FM that he made a call to check on Brady's condition and it "hopefully did not appear to be that bad." Brady tore the anterior cruciate ligament in his left knee in the 2008 season opener and missed the rest of the season, but he has played every game since then. Brady had left tackle Nate Solder pushed into him by Tampa Bay defensive end Adrian Clayborn during a joint practice with the Buccaneers. "You've always got to stay away from the quarterback," Clayborn said. You got a guy on his heels and my instinct is to keep going, so that's what I did. Brady, a two-time league MVP entering his 14th NFL season, rocked backward on the ground after falling down and held his left knee. He went to the sideline, then returned for a few more plays before talking with Belichick and leaving the field for good. More trouble for Miller Denver Broncos Pro Bowl linebacker Von Miller, already facing a suspension for violating the NFL's drug-abuse policy, is now confronted by charges that he failed to show up in court on misdemeanor traffic violations. Miller was arrested in the Denver suburb of Centennial on Sunday and then released, an Arapahoe County sheriff's department spokesman said Wednesday. The Broncos released a two-sentence statement saying they and league officials are aware of the allegation that Miller didn't appear at a court hearing. The matter is "being handled through the legal system," the statement said. Miller wasn't available for comment Wednesday. He was supposed to appear in court Dec. 31 on charges of careless driving, driving without a license and no proof of insurance, Arapahoe County court officials said. The original citation was issued Oct. 25. Suspensions St. Louis Rams starting linebacker Jo-Lonn Dunbar was suspended for four games for violating the NFL's policy on performance-enhancing drugs. Dunbar, who was second on the team with a career-high 157 tackles last season, is able to participate in all team activities prior to the suspension, which begins with the season-opening game against Arizona. He will be able to practice and play in all exhibition contests prior to the opener. Dunbar made a brief statement and appeared emotional. "I just want to say that I did not take a performance-enhancing drug," Dunbar said. I mistakenly took something that prompted a failed drug test. Also, San Francisco 49ers defensive lineman Demarcus Dobbs was suspended for a Week 1 game against Green Bay for a violation of the NFL's substance-abuse policy. Oakland Raiders starting left tackle Jared Veldheer will need surgery on his torn left triceps and will miss a significant portion of the season.
