Slowed by a sprained ankle and still nursed sore right shoulder, starting quarterback Ben Roethlisberger missed a second straight day of practice on Thursday, and Pittsburgh Steelers' officials are likely to take a cautionary approach and sit the four-year veteran for Sunday's season finale at Baltimore. Roethlisberger, who on Thursday was named as the AFC offensive player of the week for his performance in a Dec. 20 victory at St. Louis, has started all 15 games this season and 30 straight games over two years. He is one of only 12 quarterbacks in the league who have started every game for their respective teams. If Roethlisberger does not play, 10-year veteran Charlie Batch would get his first start of the year. Batch has not started a game since the 2006 season opener when Roethlisberger was recovering from an appendectomy. Batch has played sparingly in 2007 and completed just one of five passes for 14 yards.
