Trent Edwards went 25-of-30 for 261 yards and a touchdown, and Kawika Mitchell intercepted a pass from Philip Rivers at the goal line to thwart a potential go-ahead score as the Bills beat the Chargers, 23-14.
Mitchell's interception allowed Edwards to engineer a seven-play, 43-yard drive to set up Rian Lindell's 44-yard field goal with 3:17 remaining. Then Mitchell came through again, when he forced Rivers to fumble on San Diego's next possession.
Edwards hit Lee Evans on a 2-yard touchdown pass and Marshawn Lynch also scored for the AFC East-leading Bills, off to their first 5-1 start since 1995. Buffalo got the 200th home win in franchise history.
Titans 34, Chiefs 10 - LenDale White rushed for three touchdowns and 149 yards, including an 80-yard sprint, and Chris Johnson broke free for a 66-yard gallop while rushing for 168 yards.

Redskins 14, Browns 11 - Clinton Portis really started piling up the yards. Santana Moss starting doing spin moves after catching the ball. London Fletcher led a huge goal line stand. The Browns, not to be outdone, made things interesting with a late touchdown, a 2-point conversion, and a field-goal attempt that was wide right with 25 seconds to play.
