From John Clayton's blog: Foster on Bills' radar? Now that Lynch is out for three games, the Bills might have to revisit the idea of signing 49ers running back DeShaun Foster. The Bills looked at him last month but didn't sign him. Fred Jackson is good enough to be the starter for the first three games, but the team needs a dependable backup to get them through September. The other option might be finding a back in the first three rounds of the draft.
