Ben Roethlisberger's ankle injury has been officially diagnosed as a grade one high ankle sprain.It's the least severe degree of sprain, but is still likely to prevent Roethlisberger from turning in much, if any, practice time this week. That being said, it shouldn't prove to be too large of an impediment for a quarterback who's made a living playing through pain. Roethlisberger may milk the drama this week, but it would be an upset if he's not under center against the 49ers. Dec 12 - 1:52 PM
