KANSAS CITY, Mo. (AP) — Pro Bowl defensive tackle Dontari Poe walked gingerly off the Chiefs’ practice field Tuesday with back pain, and linebacker Derrick Johnson sat out with inflammation in his knee. The Chiefs were getting back to work with the second week of organized team activities when Poe walked off the field. A team spokesman did not say how long he might be out.

Johnson worked out last week. He missed nearly all of last season with a torn Achilles tendon. Wide receiver Chris Conley was back on the field after missing time last week to attend the NFL’s rookie premier, while linebacker Justin Houston remained absent from the voluntary workouts after getting the franchise tag earlier this offseason.
