Veteran cornerback Vontae Davis visited both Bay Area teams last week, but he won't make either Oakland or Santa Clara home.
Instead, the 29-year-old appears to be joining the Buffalo Bills.
At 4:10pm PT, Davis tweeted out "#BillsMafia," which is the moniker used by Bills fans.
Davis' contract with Buffalo is a one-year deal, according to ESPN.
The brother of former 49ers tight end Vernon Davis, Vontae is a nine-year NFL veteran. He was released by the Colts in November after playing in just five games.
