Safety Darian Stewart wore No. 20 in St. Louis.
He wasn't about to get that number in Baltimore, however. That belongs to the legend, Ed Reed.
Stewart will instead wear No. 24.
The Ravens haven't officially retired any numbers in team history.
They simply stopped giving out No. 75 after Jonathan Ogden stopped wearing it. They didn't give out Ray Lewis' No. 52 or Reed's No. 20 last year after they retired and departed, respectively.
New guard Jeremy Zuttah has a strange number for now. He'll wear No. 53, which is the number linebacker Jameel McClain wore before heading to the New York Giants this offseason. Zuttah is currently the only offensive lineman in the 50s.
