KANSAS CITY, Mo. (AP) — Chiefs coach Andy Reid was still baffled Monday by an offside penalty called on his offense that wiped out a go-ahead, 49-yard touchdown pass against the Buffalo Bills, taking the officiating crew from Sunday's game to task for throwing a flag rather than issuing a customary warning in that situation.

The play came with just over a minute left and the Chiefs trailing 20-17. Patrick Mahomes threw over the middle to Travis Kelce, who was about to get tackled when he lateraled to Kadarius Toney, who ran untouched the rest of the way for the score.
