After four weeks the surprising Kansas City Chiefs are one of five undefeated teams left in the NFL, and next face the Tennessee Titans on Sunday afternoon at LP Field.

Under head coach Andy Reid, the Chiefs have already doubled their wins from last season, and gun for the third road victory that took 13 weeks for the 2011 squad to reach.

The 3-1 Titans would be riding high off their 38-13 victory over the New York Jets last week, had it not been for the hip and knee injuries sustained by emerging quarterback Jake Locker. Locker could reportedly be out for upwards of six weeks, while Tennessee begins a daunting part of its schedule against the Chiefs, Seattle, and San Francisco before the Week Eight bye.

Former Buffalos starter and veteran Ryan Fitzpatrick will fill in for Locker in the meantime.

Kansas City quarterback Alex Smith is currently tied for ninth in the NFL with seven touchdown passes, and running back Jamaal Charles has totaled 502 yards and four touchdowns from scrimmage.

But the Chiefs main threat is their second ranked pass defense, allowing 188.8 yards per game thanks to veteran corners Brandon Flowers and Dunta Robinson, and safety Eric Berry.

That’s without mentioning the pressure upfront from Justin Houston, the third year linebacker tied for an NFL-best 7.5 sacks. As a team, Kansas City is also tied for tops in the NFL with 18 sacks.

Fitzpatrick, along with leading running back Chris Johnson and receiver Nate Washington, will try to keep the Titans perfect home record intact, but much of the burden could fall on the 10th ranked total defense.

Along with holding opponents to a seventh best 17.3 points per game, linebacker Zach Brown and defensive tackle Jurrell Casey each have three sacks, and fourth year defensive back Alterraun Verner has hauled in an NFL-high four picks.

Other than Locker, the Titans will also miss defensive tackle Sammie Lee Hill, as well as reserve running back Shonn Green due to a knee injury.
