Matt Birk, a six-time Pro Bowl center from the Minnesota Vikings, will be making a free-agent visit to the Ravens, according to the Minneapolis Star-Tribune.
Birk's visit has not been confirmed by the Ravens and calls to his agent have not been returned. It is uncertain when he will visit.
The Ravens are looking to replace center Jason Brown, who signed with the St. Louis Rams last week.
According to a couple reports out of Minnesota, the Vikings are still interested in Birk and could attempt to match any offer. Birk has spent his entire 11-year career with the Vikings.
Birk, 32, is a 6-foot-4, 309-pound center who was a sixth-round pick out of Harvard in 1998.
Last season, he was selected to his sixth Pro Bowl, tying Mick Tinglehoff for most Pro Bowl appearances by a Vikings center.
Birk has taken a leading role in the Gridiron Greats program, which assists former players who face severe health and financial hardships. He donated $50,000 and also sent a letter to every NFL player encouraging them to donate a portion of their Dec. 21 game check. Only about 20 players donated to the cause.
The Ravens' other options at center are moving Chris Chester or Marshal Yanda to center. Both spent time at that position during minicamps and training camp, backing up Brown.
