"I don't know my future really, what I'm going to do," Schobel told two reporters, including The Associated Press, following practice Wednesday.
Wawrow also notes that Schobel fears he has "slowed down" in his ninth season out of TCU. He'll be 33 at the start of the 2010 season, and at that point will be in the fourth year of a 7-year, $50 million deal he signed in August of 2007.
Schobel has 7 sacks this season after missing the majority of the 2008 season with a Lisfranc foot injury. His 75 career sacks are second in Bills team history, behind Hall of Fame end Bruce Smith.
