Despite generating only 229 yards in Sunday night's blowout loss to New England, quarterback J.P. Losman has retained the Buffalo Bills' starting job for next Sunday's key conference matchup at Jacksonville. It will mark the fourth straight start for Losman who opened the season as the starter and then lost the job to rookie Trent Edwards when he suffered a left knee sprain on Sept. 23. Edwards started four straight games, winning three of them, then suffered a sprained right wrist. The injury allowed Losman, the team's first-round choice in the 2004 draft, to reclaim the No. 1 spot on the depth chart. Buffalo has won two of its last three outings with Losman back in the lineup but was blown out, 56-10, by New England on Sunday night. The defeat was the worst in franchise history.
