We wondered earlier today what was going on with Kansas City Chiefs WR De'Anthony Thomas, who has been mysteriously absent from practice for non-injury related reasons.

Chiefs coach Andy Reid said earlier that GM John Dorsey was handling it and so now the Chiefs have announced that they have put DAT on the NFI list, which means his season is over.

(Adam Schefter previously reported it was IR but it's NFI; regardless, the result is the same)

DAT suffered a concussion on November 22 but returned to practice last week. The Chiefs then ruled him out a day before last week's game and DAT did not return to practice this week, which left us wondering what was going on. I still don't know what's going on. Wishing him all the best.

The Chiefs will survive without DAT because they've won five straight games without him already. He was the top punt returner but Frankie Hammond has assumed those duties.

His season ends with 17 receptions for 140 yards and one touchdown receiving and rushing.

This means that the Chiefs now have an open roster spot they can fill before the playoffs get started after this week.
