Ravens center Matt Birk should be coming off the Physically Unable to Perform (PUP) very soon, according to coach John Harbaugh. Birk had minor surgery on his elbow this offseason. He is constantly working after practice. "Matt’s getting very close," Harbaugh said. "He’s getting antsy. I think we’ll be seeing him very soon." The timetable is not as clear for backup offensive tackle Tony Moll, who has a concussion. "The symptoms have to clear up," Harbaugh said. "Obviously, they’ll always be very careful with that."
