During a press conference on Monday, Chiefs coach Andy Reid offered his condolences to Matthews' family.

Kansas City is 9-1 this season and will play the 9-1 Rams in Mexico City next Monday.
Mahomes isn't expected to miss any playing time either, though Reid said, "If he has to, that's not a big deal".
