According the John Clayton of ESPN.com, the Baltimore Ravens have signed QB Todd Bouman to back up rookie Joe Flacco.  Here is the story from Clayton:

Veteran Todd Bouman, one of three veterans to work out for the Ravens Tuesday, accepted a one-year offer to sign with the team, a source said.

Bouman worked out Monday in Baltimore against Chris Simms and Joey Harrington. On Tuesday morning, he was offered a one-year deal at $830,000.

The 36-year-old Bouman will be joining his sixth team. He was an undrafted quarterback when he signed with Vikings in 1997. Hes been in Minnesota, New Orleans, Green Bay, Jacksonville and St. Louis.

The Ravens named Joe Flacco as the starting quarterback Monday but have injury concerns with Troy Smith and Kyle Boller. Smith has infected tonsils and Boller has a torn labrum in his shoulder and might need surgery.

This is what I wanted all along, Flacco said Monday. Things happen funny. Ive gotten my opportunity, and now its up to me to go out there and play.

They turned down Chris Simms ??? Makes you wonder if Simms is 100%
