The AFC's top two rivals meet in a pivotal Week 9 showdown on Sunday, Nov. 2, as the Buffalo Bills (5-2) defend home turf against the Kansas City Chiefs (5-3).

Halloween may have come and gone, but the Chiefs and Patrick Mahomes remain Josh Allen's boogeyman. Kansas City again ended Buffalo's Super Bowl hopes during the Allen era earlier this year when they snatched a 32-29 AFC championship game victory.

Now, the two teams could be on a playoff collision course yet again. The Chiefs are getting right after returning Rashee Rice from suspension and have put blowout wins on the board in each of their last three games.

While the headlines go to Mahomes, the credit might lean towards KC's D. The Chiefs defense enters Week 9 as one of the best units in football, ranking second in points allowed and fourth in yards allowed.

The Bills turned in a 40-9 win over the Carolina Panthers in Week 7, getting right themselves after a short two-game skid with losses to the New England Patriots and Atlanta Falcons. Now, they look to use their Week 8 bye to rest, rejuvenate and catapult them into more wins as the playoff push begins – and maybe they'll find some trade deadline help along the way.
