In a move that could impact the offensive game plan for Sunday's game against the Carolina Panthers, the Ravens waived offensive tackle Scott Kooistra to make room for guard Bryan Mattison on Saturday.
The roster move suggests that the "skin issue" – as coach John Harbaugh called it – that hospitalized starting right guard Chris Chester Thursday night and forced him to miss Friday's practice is more serious than initially thought. Chester was listed as questionable on the team's injury report for Sunday's game.Chester, who has started all nine contests, has been flagged just once this season for holding and has surrendered just two sacks, according to Pro Football Weekly. One of Chester's strengths is his nimble feet, which help him pull and spring running backs Ray Rice and Willis McGahee.
Tony Moll, who took all of the snaps during practice at right guard, would likely replace Chester. Moll, who could make his first start at that spot since Sept. 21, 2008, was drafted by the Green Bay Packers in the fifth round of the 2006 draft as a guard.
The promotion of Mattison, the son of defensive coordinator Greg Mattison, from the practice squad fortifies the interior of the offensive line if Chester is indeed unavailable for Sunday.
