The Chargers will host the Bills on Saturday night, and owners should at least have plenty of notice for a backup plan if Allen doesn't play. As we said last week, the Bolts have no reason to rush Allen back into their lineup. Palmer could be a replacement option if he's on your wire, and had a big game in Week 15. However, the Chargers trailed the Raiders and had nothing to lose on the offensive side. The Bills proved to be a tough matchup against the Cowboys in Week 15 against the Cowboys.
