​In case you still thought the ​Chiefs had a secondary following their last-minute gag against the Chargers, we've got an unfortunate update for you.

Per reports, star corner ​Kendall Fuller played Thursday's AFC West showdown through a painful wrist injury that may or may not be a fracture. Fuller will have surgery early Friday to correct the issue, knocking him out for the year.

​​Fuller, the prize of the Alex Smith trade with the Redskins, has now been erased from the equation as we hit the season's final weeks.

And yes, he even picked one last night with a busted wrist.

Needing to win out to maintain their division lead (and having already lost three primetime games this season), Kansas City now goes on the road to Seattle to face the 12s next Sunday night before wrapping the regular season up with a home game against Oakland. Win both, and they're the AFC's top seed. Drop one, and the playoffs could run through something called the "StubHub Center."

Crazy turn of events.

The Chiefs secondary has already had a difficult time maintaining their footing this year, and will lose Fuller just as they welcome Eric Berry back. Right back to the drawing board for a scuffling unit that can't stay intact.
