Free agency has been tough so far for the Vikings, who have lost out on some players, and may be close to losing another one, this time one of their own.

Reports say that center Matt Birk is “absolutely” considering making a jump to the Ravens. The Baltimore Sun states that it is believed Birk will decide whether to sign with the Ravens or Vikings during the next two days. “I wouldn’t be here if I didn’t think it was a strong possibility,” Birk said while standing in the 24-degree weather in a T-shirt. “Me and my wife wouldn’t have come out here and looked around” if it weren’t a good chance.
