Reed also was a no-show for the mandatory veteran minicamp earlier this offseason. The eight-time Pro Bowl selection is entering the final season of his contract.
Running back Ray Rice, wide receiver Anquan Boldin and linebacker Terrell Suggs also reported to camp this morning. Asked if he was happy to be back, Rice, the recipient of a huge contract extension last week, said, "The smile says it all."
Suggs, who is expected to miss a good part if not all of the 2012-13 season after tearing his Achilles in the offseason, was not wearing a walking boot.
The Ravens' first full-team practive is Thursday.
