Flacco disclosed Monday morning that his wife, Dana, is expecting their second child. They were both on hand for the Super Bowl Most Valuable Player news conference, where he was presented with the keys to a 2014 Corvette Stingray.
Flacco said they learned of the news just two weeks ago.
The high school sweethearts had a son on June 13 named Stephen Vincent Flacco, who was born at eight pounds.
The Flaccos told their family about the first pregnancy at Thanksgiving 2011 -- when the team also played the San Francisco 49ers.
"It's a good luck thing," Joe Flacco said.
