The Buffalo Bills and Kansas City Chiefs will face off in the game of the week on Sunday in Week 9.
Even once that massive clash of the titans is over, though, their competition may not be over for the week.
The NFL trade deadline is Nov. 4 (Tuesday), and the Bills and Chiefs are both expected to be active.
There's one guy both teams could be after, too, writes ESPN's Bill Barnwell: Calais Campbell.
The 6-foot-8 defensive tackle is likely a future Hall of Famer and has been productive for the Arizona Cardinals, even at age 39.
"Campbell is continuing to play at a high level, and he might want to simply finish his career where it started in Arizona, but the 39-year-old is good enough to play meaningful snaps on a team that's competing for a Super Bowl," Barnwell writes. "He would be a great fit for a team like the Chiefs or Bills, both of whom could use extra depth up front."

The Bills just lost Ed Oliver for at least the rest of the regular season with a torn biceps.
The Chiefs' defensive line remains led by Chris Jones but has underwhelmed in a few key spots this season.
Campbell brings a lot of versatility, still able to line up inside or outside on the line as needed.
The big guy has 113.5 career sacks, including 3.0 this season. He spent his first nine seasons with the Cardinals, then went to the Jaguars, Ravens, Falcons and Dolphins, before returning to Arizona this season.
He'd be a huge pickup both on the field and in the locker room for either Buffalo or Kansas City. If he's truly available, they'll take that battle right to the trade deadline.
