Jenkins (knee) didn't participate in practice Wednesday, Nick Wagoner of ESPN.com reports. Jenkins has tallied a wide range of tackles this season -- between two and nine -- en route to 29 tackles (27 solo) and an interception for a touchdown through six outings. Meanwhile, he was able to return to action Sunday after initially suffering a knee injury, meaning his absence Wednesday may be a precaution. Friday's injury report could clarify his availability for Sunday's outing in Kansas City.
