The Facts: Brown sustained a concussion in the second half of Sunday's win over the Lions.

Diehards Line:The injury left the Giants with just one healthy running back: rookie Michael Cox. HC Tom Coughlin said he didn’t have an update on Brown Monday afternoon. “I’m naturally concerned,” Coughlin said. “Andre Brown. Is he going to be able to work and play? He felt pretty good on the plane (Sunday) night but that doesn’t mean anything. Veteran Peyton Hillis, who sat out vs. Lions with a concussion, may be ready to return this week. If so, he would likely get the start if Brown can't go.
