Lions coach Jim Schwartz has moved into regular-season mode on injury information, but he told reporters that no player on the roster has a "long-term injury," which he defined as: "Their season is in jeopardy or they're going to be out for a while," according to Tim Twentyman of the Lions' web site.
That designation includes rookie tight end Michael Williams, who had surgery Monday to repair a bone in his hand, according to his agent. It also apparently applies to running back/special teams ace Montell Owens, who crumpled to the ground Thursday after a non-contact knee injury.
Schwartz said he plans to use most of his healthy regulars in Thursday's preseason finale at the Buffalo Bills. But it's safe to assume that Owens and Williams will sit out that game and be in doubt for Week 1 of the regular season.
