OWINGS MILLS, Md. — As the Ravens move closer to taking on their hated rivals from Pittsburgh to begin the season on Sunday afternoon, they appear to be getting healthier just in time for the occasion. All 53 players on the active roster were present and working during the open portion of Wednesday’s practice, including center Matt Birk (knee), wide receiver Lee Evans (foot), and cornerback Chris Carr (hamstring). All three were dressed in full pads and did not appear to be limited in the early stages of the workout. With primary kick returner David Reed suspended in the regular-season opener for violating the NFL’s substance-abuse policy, cornerback Lardarius Webb appeared to be the primary returner during the special teams portion of practice. Rookie receiver Torrey Smith also fielded kicks. For anyone trying to find some clarity in what the Ravens plan to do at the center position, Birk was snapping to starter Joe Flacco while newcomer Andre Gurode snapped to rookie backup Tyrod Taylor during individual drills.
