Taking over after Kelly Holcomb hurt his head in the second quarter, J.P. Losman engineered touchdown drives on two of his first four possessions to lead Buffalo.
Losman finished 9 of 16 for 137 yards, hitting Lee Evans for both touchdowns. Losman was focused and efficient, looking nothing like the hesitant first-year starter who went 1-3 before being replaced by Holcomb following a 19-7 loss to New Orleans on Oct. 2.
Holcomb was shaken up when his head snapped back after he was sacked by Jared Allen and lost a fumble. Losman took over on the next possession and led a seven-play, 66-yard drive capped by a 33-yard touchdown pass to Evans, giving Buffalo a 7-3 lead.
The Bills, coming off their bye week, snapped a two-game losing streak and won with a defense further depleted by injuries.
DT Sam Adams missed his first game of the season because of a knee injury and veteran FS Troy Vincent hurt his shoulder in the second quarter and didn't return.
The defense played well, limiting the Chiefs to 316 yards while generating three interceptions, a fumble and six sacks. Kansas City's three points were the fewest Buffalo has allowed since the Bills beat New England, 31-0, in the 2003 season opener.
Kansas City lost its fifth straight game at Buffalo and failed to build off last weekend's last-second win over Oakland.
