SANTA CLARA, Calif. Mark Jackson Jersey . - The San Francisco 49ers might be getting closer to adding a couple of big names back to their injury-depleted defence.Linebacker NaVorro Bowmans 21-day evaluation window is set to begin Tuesday. That means he could start practicing again this week as the Niners determine whether he will be able to play this season following a devastating left knee injury in last Januarys NFC championship game that required surgery.With NaVorro, well see where he falls and how much he can do, coach Jim Harbaugh said, noting Bowman initially might be limited to walk-throughs or individual drills.Bowman tore the anterior cruciate and medial collateral ligaments in his left knee in the loss to eventual Super Bowl champion Seattle.On Monday, San Francisco activated nose tackle Glenn Dorsey following his 21-day stretch, putting him in position to play for the first time Sunday at home against Washington if he is deemed ready by the coaches and medical staff.Dorsey tore his left biceps Aug. 1 and required surgery. He was placed on the injured reserve/designated to return list with the hopes he would be able to come back this season.San Francisco cleared room on the 53-man roster for Dorsey by placing nose tackle Ian Williams on season-ending IR because of a fractured left fibula suffered at New Orleans on Nov. 9. Its been a rough two seasons for Williams, who was sidelined last year following a Week 2 ankle injury against Seattle that required several procedures. Williams was in a walking boot and using crutches last week.The 49ers (6-4) withstood a daunting two-week stretch by winning close games at New Orleans and New York, the latest victory coming in a week that San Francisco lost star linebacker Patrick Willis for the season and also rookie cornerback Jimmie Ward. And, now, Williams.The backups have been stellar, while the regular faces in the secondary have done their part. Cornerback Chris Culliver sprinted up to Harbaugh with his interception game ball Sunday and handed it off to the coach along with a hug.He competes like a maniac, Harbaugh said of Culliver, who missed last season with his own serious knee injury.Rookie linebacker Chris Borland piled up some more big numbers.Borland, who has filled in since Willis injured his left big toe at St. Louis on Oct. 13, had two of the five interceptions against Eli Manning in Sundays 16-10 road win against the Giants. He also added 13 tackles, giving him 48 over the past three games.Theyre young guys stepping up, running back Frank Gore said. Coach, every week he challenged the young guys who got the opportunity to play, and theyre stepping up to the plate.Also Monday, Harbaugh said he spoke to linebacker Ahmad Brooks, who played just 12 snaps Sunday. Brooks played just a few snaps — and none in the second half — after Aldon Smith entered early in the second quarter to make his season debut following a nine-game suspension.After the game, Harbaugh said, We have something were working through.Harbaugh said a day later that he expects Brooks to play against the Redskins. With the emergence of rookie linebackers Borland and Aaron Lynch and with Smiths return, Brooks playing time could diminish.Yes, weve addressed it and had those conversations, onward, Harbaugh said. Yeah, I can be specific, I can be very specific. Its something I dont want to share with you or share publicly.___AP NFL websites: www.pro32.ap.org and www.twitter.com/AP_NFLTim Hardaway Jr. Jersey .

The Toronto Argonauts running back hurt his left ankle during the teams practice Friday afternoon at Rogers Centre. OMAHA, Neb. -- Virginia pitcher Josh Sborz slips a pinch of chewing tobacco between his cheek and gum every now and then, even though the NCAA banned the substance 20 years ago, "I enjoy the taste. Its not like Im addicted to it," Sborz said. "I just enjoy it, definitely. I do it maybe once a month or every other week." Sborz said this weeks death of Hall of Fame baseball player Tony Gwynn might give college players some pause. Gwynn died at 54 of oral cancer believed to be connected to his long use of chewing tobacco. "It should have an impact when such a star-studded players life was ended by the addiction he had. Its sad," Sborz said. Whether Gwynns death has any real impact is an open question and it comes amid some concerns: Baseball players acknowledging using spit tobacco at least once in the previous month rose from 42.5 per cent in 2005 to 52.3 per cent in 2009, according to the NCAAs quadrennial survey substance use trends among its athletes. Results of the 2013 survey have not yet been released, though preliminary results suggest a drop since 2009. About 15 per cent of teams in each NCAA sport are asked to participate in the anonymous survey, with a total sample size of about 20,000 athletes. Among all male athletes, 16 per cent acknowledged using tobacco in 2005 and 17 per cent in 2009. Sborz said he thinks the survey is "skewed" when it comes to ball players. "All those people dont do it every day," he said. "If people do it every day, thats where it becomes a problem. If they do it once every week, I dont see any issue with it." Minor-league baseball banned tobacco in 1993, a year before the NCAA. Tobacco is not banned in the major leagues. Though tins of tobacco arent visible in college dugouts like they were before 1994, that doesnt mean players arent dipping when theyre away from the ballpark. "Its 100 per cent part of baseball culture," said Virginia second baseman Branden Coogswell, who estimated half his teammates chew tobacco at least occasionally. Carl Braun Jersey. "Its kind of a habit for people, kind of a comfort thing. Ive never been a part of that group, but so many guys do it. People take those risks. Its their choice." Dave Keilitz, executive director of the American Baseball Coaches Association, said he was surprised to find out so many baseball players were using tobacco. "I think most of our coaches, if not all of our coaches, are very aware of the danger and also dont want their players using it," Keilitz said. "In my 20 years of doing this, I havent seen any evidence of that taking place in dugouts, in games. I hope the same holds true in practice sessions." Keilitz said his organization adamantly opposes the use of smokeless tobacco and participated in the making of a video that illustrates the dangers. Virginia coach Brian OConnor said he chewed during his playing days in the late 1980s and early 90s. Like Keilitz, he was surprised so many players acknowledge using tobacco. "If kids are doing it, theyre doing a heck of a job of hiding it," he said. The NCAA said the ban was put in place as part of its charge to protect the safety and welfare of athletes. The penalty for violating the ban was left to the committee that oversees each sport. The Baseball Rules Committee instructed umpires to eject any player or coach who is using tobacco or who has tobacco in his possession. Enforcement was spotty until the committee made it a point of emphasis in 2003. In spite of the warnings the players receive, Texas coach Augie Garrido said he knows some members of his team chew tobacco. "Theres a lot more of it in Texas," he said, "because its not only about the baseball. Its about hunting, its about fishing, its about being a man." As for Sborz, he started chewing for a simple reason. "I saw an older kid do it, so I thought Id try to do it," he said. ' ' '
