Ravens sign Pats practice squad CB

The Patriots have an opening on their eight-man practice squad, as cornerback Prince Miller has been signed to the Baltimore Ravens' 53-man active roster.

The Ravens announced the move on Twitter.

The Patriots had quarterback Keith Null in for a tryout this week and perhaps he will fill the open spot on the practice squad. The Patriots only have two quarterbacks on the active roster -- Tom Brady and Brian Hoyer -- and don't currently have a quarterback on the practice squad.
