Today in sports: New Patriots quarterback Tom Brady pitches American males on Ugg boots, Chicago Bears Lance Briggs won't be fined for his 9/11 uniform tribute, and another scary new concussion study emerges.

  • New England Patriots quarterback Tom Brady is a three-time Super Bowl champion, Gisele Bundchen's boyfriend, and a source of hope for every longshot pro athlete trying to crack a roster. He's also the new male spokesman for Ugg boots, which is launching a new marketing campaign to prove that furry boots aren't just for women. Based on Brady's performance in his first TV spot for the company, which will air on ESPN during Monday Night Football, we remain unconvinced. [Ad Week via Deadspin]

  • The NFL announced Friday that Chicago Bears linebacker Lance Briggs wouldn't be fined for wearing a stars-and-stripes themed shoe and glove combination during Sunday's game against the Atlanta Falcons, which is probably wise. Nothing good can come from telling someone trying to pay his respects to the victims of 9/11 that their gloves and shoes are overly patriotic. [@55berger and ESPN Chicago]

  • For those who want a new sobering, scary concussion study to go with the first weekend of NFL football, researchers at Brown University say in a new study published in the Journal of Biometrics that running backs and quarterbacks suffer the most severe types of head injuries, while linebackers absorb the highest frequency of head shots. The results come from three years spent documenting 286,636 helmet-to-helmet hits in games and practices at Brown, Darthmouth, and Virginia Tech. Players had their helmets equipped with a special sensor that allowed researchers to measure "magnitude, frequency, and location of head blows." That number could then be weighed against "each player's head impact exposure" to assess the risk of a concussion on a position-by-position basis. [Science Daily]
