Due to an abbreviated window to watch practice, there wasn't enough time to account for every player Thursday.
But center Matt Birk was not present during the portion of practice open to the media. Birk did not practice the past two Wednesdays because of a left knee injury, but he did return on Thursday and Friday and did play in the Ravens' 30-7 victory over the Kansas City Chiefs in Sunday's AFC Wildcard playoff game.
Also, cornerback Chris Carr appeared to be absent. He was limited Wednesday with a thigh injury.
Wide receiver Donte' Stallworth, who sat out Wednesday's session due to illness, was back. Safety Tom Zbikowski (bulging disk in back) and linebacker Tavares Gooden (dislocated left shoulder) – both of whom fully participated Wednesday – were also active.
