The Chiefs hosted the 5-8 Chargers on December 14, hoping to end their slim playoff chances. Temperatures which hovered in the low 60s when early-arriving fans first showed up plunged into the 20s by the end of the game. The Chiefs dominated the game early, leading 14-3 at halftime. Chiefs quarterback Tyler Thigpen threw for one touchdown and ran for another for the Chiefs and was 19-for-28 for 171&#160;yards. The Chargers had three turnovers and, perhaps more embarrassing, gave up three sacks to the NFL's worst pass rush. Tamba Hali had two sacks and caused two fumbles for a Chiefs defense that hadn't gotten a sack since playing San Diego four games ago. The three sacks pushed Kansas City's season total to a league-low nine, and the Chiefs need five in their last two games to avoid tying the NFL record for fewest in a season. Five of the sacks from the season have come against San Diego. Leading into the fourth quarter, Kansas City led 21-10, but allowed 11 points in the final 79&#160;seconds of the game to lose 22-21. The Chiefs, despite having an 18-point lead, used up all three time-outs. The victory sealed a season sweep for San Diego over Kansas City, with both victories ending in a one-point margin. The day after the Chiefs' loss to San Diego, Chiefs owner Clark Hunt announced the resignation of Carl Peterson from all positions held (general manager, vice president, and chief executive officer) effective at the end of the season. The official press release stated that Peterson resigned, but Hunt had said the conversation had been on-going throughout the season. Hunt said his decision to relieve Peterson of duties was not based on what happened the previous day, when the Chiefs lost an 11-point lead in the final 73&#160;seconds and were beaten 22-21 by San Diego, dropping their record to 2-12. Hunt also said that the fate of head coach Herman Edwards would be settled after the season. Hunt said he would split the duties previously held by Peterson and have someone in charge of the business side and someone else in charge of football for the franchise. Hunt said he plans on hiring someone from outside the organization.. How many sacks did the Chiefs defense have?
