The Chiefs signed offensive tackle Ray Willis and waived fullback Taylor Gentry.
Kansas City needed to add another veteran offensive tackle when Tony Ugoh decided to retire after being signed last week.
"He retired from the game and there's nothing we can do about that," Chiefs coach Romeo Crennel said. "You've got to have a desire and you've got to have your mind clear on all your problems and things out of the way to try to play this game."
Willis spent his first five seasons with the Seahawks and has also spent time with the Dolphins and Jets. He was released by the Jets in June. He has played in 44 NFL games with 26 starts.
Gentry was signed as an undrafted rookie out of North Carolina State in May, but Crennel said he would not be able to pass the team's physical for medical reasons.
"I think that that's something that if he chooses to talk to you about them, he will, but he's not going to pass the physical so he no longer will be with us."
--Wide receiver Junior Hemingway will be rested "a little bit" due to a strained groin.
"Because he does work hard, I think that he'll be able to catch up pretty quickly," said Crennel.
