Kansas City Chiefs safety Eric Berry (ankle) will not play against the San Francisco 49ers on Sunday.

The team also listed wide receiver Donnie Avery, who had surgery Friday morning, as out for the game. In the Chiefs’ 41-14 blowout win over the New England Patriots on Monday night, Avery suffered a core muscle injury.

“Eric Berry is making progress, but still not able to play,” coach Andy Reid said Friday.

“Look forward to the challenge of playing the 49ers. These guys have had a good week of practice. We know we’re playing against a good football team. We tried to focus in on trying to get ourselves better and then going out there and playing and, again, against a good football team.”

Reid also said that rookie running back De’Anthony Thomas is expected to make his debut after missing the first four games due to a hamstring injury.

“De’Anthony, he’s good to go,” Reid said.
