KANSAS CITY, Mo. (AP) – Chiefs wide receiver Jeremy Maclin will miss his fourth straight game Sunday at Atlanta, while cornerback Phillip Gaines was added to the injury report as questionable with a knee injury. Maclin had been questionable with a lingering groin injury on the final injury report Friday.

The Chiefs also promoted defensive lineman T.J. Barnes from the practice squad Saturday, likely as insurance in case Dontari Poe or Kendall Reyes is unable to play. Poe is questionable with back spasms and Reyes has been dealing with a knee injury.

The Chiefs are coming off an overtime victory in Denver on Sunday. After playing the Falcons, they face a short week, with AFC West rival Oakland on Thursday night at Arrowhead Stadium.
