KANSAS CITY, Mo. (AP) — The Kansas City Chiefs are off to a 4-0 start. Yes, the same Chiefs that went just 2-14 last season.

The Chiefs pounded the New York Giants 31-7 on Sunday to keep their perfect record intact, though they didn’t come out of it unscathed. Right tackle Eric Fisher is being monitored after a suspected concussion and running back Jamaal Charles has badly blistered feet.

Chiefs coach Andy Reid said Monday he’ll leave Fisher’s status up to the team’s medical staff, but he believes that Charles will be OK for next Sunday’s game at Tennessee.
