KANSAS CITY, Mo. (AP) – The Kansas City Chiefs have traded backup running back Knile Davis to the Green Bay Packers, who desperately need to add depth to their injury-riddled backfield.

The Packers gave up a conditional draft pick Tuesday for Davis, who has already started practicing with his new team.

The Packers needed help at running back with Eddie Lacy nursing a bothersome ankle and James Starks undergoing knee surgery. Lacy was their only active running back against Dallas on Sunday, when he rushed for 65 yards on 17 carries in a 30-16 loss.

Starks will be out a couple of weeks. Lacy was being held out of practice Wednesday because the ankle was “very sore,” coach Mike McCarthy said.

That means the Packers will have to get Davis up to speed on the playbook quickly if he’s going to be ready when the Chicago Bears visit Lambeau Field on Thursday night.

The Davis deal was the start of a slew of roster moves on Tuesday for Kansas City. The Chiefs signed free agent defensive lineman Kendall Reyes, who was with Washington for two games this season. He previously played four years in San Diego.

Kansas City added cornerback Terrance Mitchell, defensive lineman Rakeem Nunez-Roches and linebacker Ramik Wilson from its practice squad.

Defensive end Allen Bailey and linebacker Justin March-Lillard were placed on injured reserve. Defensive lineman Nick Williams was waived.
