Lions DE Kyle Vanden Bosch has had one of his most productive seasons from a pass-rushing standpoint, recording eight sacks — one in eight separate games. What's more, he has played in every game to date. The subjects are related. Vanden Bosch missed the final five games a season ago with a neck injury. Although he didn't practice on Tuesday or Wednesday because of his neck, he returned to practice on Thursday on a limited basis leading up to the Week 16 game vs. San Diego. Vanden Bosch, 33, had a pair of double-digit sack seasons in Tennessee but hadn't exceeded five sacks since 2007. The way we hear it, there's no reason to think Vanden Bosch won't be in Detroit's 2012 plans if he's healthy and productive. The Lions' other starting defensive end, Cliff Avril, is having a banner season, notching a career-best 11 sacks, including two in each of the past two games. The Lions are expected to work to keep the 25-year-old Avril, an unrestricted free agent at season's end, though it certainly won't be cheap, whether it's via a contract extension or the franchise tag, given his age, production and position.
