KANSAS CITY, Mo. (AP) — The Chiefs had no additional positive COVID-19 tests Wednesday, one day after seven players were added to the reserve list, a promising sign that an outbreak that infected 16 players in all may have subsided. Now, the question facing the Chiefs is whether they will have such stars as wide receiver Tyreek Hill, tight end Travis Kelce and defensive tackle Chris Jones available in time for Sunday’s game against Pittsburgh. They did get some positive news with wide receiver Josh Gordon and linebacker Willie Gay Jr. testing negative and returning to practice, but there are still plenty of holes in the roster and the Chiefs are running out of time to get those players back.
