Lions have signed RB Bo Scarbrough to the active roster and waived RB Paul Perkins. Don't be surprised if Scarbrough gets some work tomorrow against Dallas. He's a much bigger back than what Detroit has on the roster already — 6-1, 235 — and could end up filling in for Nick Bawden if he can't go. Bawden is questionable with a foot injury. Also, the Lions signed P Matt Wile to the practice squad.
