Eagles coach Andy Reid says Vick doesn't have any broken bones, though the cartilage between his second and third rib might be cracked.
Reid wouldn't rule out Vick for the 49ers' game, saying Vick's sore and will be evaluated each day. Kevin Kolb, who began the season as the Eagles' No. 1 quarterback, would start if Vick can't play.
Running back LeSean McCoy did break a rib during the first half of Sunday's 17-12 loss to the Washington Redskins but played through it. His status also is uncertain. And Pro Bowl cornerback Asante Samuel and wide receiver Riley Cooper sustained concussions.
