Last month, Ravens linebacker Brendon Ayanbadejo came out in favor of expanding the legal definition of marriage to include folks of the same gender. Over the weekend, Ravens center Matt Birk voiced his opposition to it in an op-ed that ran in the Minneapolis Star Tribune.

“I think it is important to set the record straight about what the marriage debate is and is not about, and to clarify that not all NFL players think redefining marriage is a good thing,” Birk wrote.

On Monday, Birk said he won’t let the issue become a “circus” in the locker room, but he also said he won’t remain silent.
