Ravens coach John Harbaugh confirmed at today's news conference that the center's wife, Adrianna, gave birth to the couple's sixth child, a boy. Tweets between some of Birk's teammates said the name of the boy was Brady.
After 11 seasons with the Minnesota Vikings, Birk, 35, has spent the last three seasons with the Ravens after signing as a free agent in 2009.
His H.I.K.E. foundation has been very active in the Baltimore community since he arrived.
