Because he was released and went on the waiver wire Wednesday, Manning is allowed to negotiate and sign with any club immediately; he does not need to wait until the free-agent period that begins Tuesday.
Chiefs owner Clark Hunt confirmed in an interview with NBC Sports Network that his team is pursuing Manning.
"I don't know how important money will be to him, but I'm sure it will be part of the equation," Hunt said. "He's going to be looking for an environment that he's comfortable in."
He declined to say whether the Chiefs already have offered Manning a contract.
"I don't think it would be appropriate for me to talk about discussions at this point," Hunt said, "but he is somebody that we'll want to talk to."
