Kansas City's opportunistic defense made up for its own deficiencies as well as an Alex Smith-led offense that managed just 210 yards. Buffalo (3-6) had a season-best 470 yards of offense.
Tuel, an undrafted rookie, struggled in his first NFL start. He went 18 of 39 for 229 yards passing with a touchdown and two interceptions while filling in for interim starter Thad Lewis, sidelined by bruised ribs.
