Former Baltimore Ravens center Matt Birk made news last month when he boycotted a visit by the Super Bowl champions to the White House because of President Obama's views on abortion.

Birk was upset that the president said "Planned Parenthood. God bless you," during a speech at a Planned Parenthood conference in April, noted the Los Angeles Times.

Birk appeared on the Family Research Council's radio show "Washington Watch" on Tuesday and told host Tony Perkins about two NFL players who were supposedly "against traditional marriage" (audio below).

"In fact, with the Ravens, we had one player who was very outspoken and was really against traditional marriage, and he got a lot of headlines," said Birk.

"One of my former teammates on the Vikings was the same way, and got a lot of press, but at the Baltimore Ravens we had six guys sign a statement that said, 'We unequivocally believe that marriage is defined as one man and one woman.'"

Birk didn't call out anyone by name, but was likely referring to former Ravens linebacker Brendon Ayanbadejo and former Vikings punter Chris Kluwe, who have both been supportive of gay couples being allowed to marry, reported

However, neither has verbally opposed the "traditional marriage" of one man and one woman.
