The Kansas City Chiefs activated defensive back Sanders Commings from injured reserve and waived safety Bradley McDougald, the team announced Tuesday.
Commings, a fifth-round pick from Georgia this year, broke his collarbone at the team's first practice of training camp.
"All the indications are that he's made really nice strides for the last couple of weeks," Chiefs general manager John Dorsey told ESPN.com. "He's physically held up. He's moved around athletically. It's the combination he gives to you in terms of being able to play safety, corner and special teams. He gives you a little bit more speed, gives you a little bit more length and size."
McDougald, an undrafted free agent who played at Kansas, appeared in one game, playing on special teams. He spent three weeks on the practice squad.
