His source says an announcement will come within the next 24 to 48 hours.
This would mean a reunion between Weis and Chiefs head coach Todd Haley, who spent time together as assistants for the New York Jets.
"Charlie's a guy I have a great amount of respect for as a coach," Haley said Wednesday at his final news conference of the season. "He's a coach that system-wise, I would say we're as close as you can be. Charlie's a guy I consider a friend and I've talked to throughout the year, no different from some of the other guys I lean on for things and advice."
The rumor mill had Weis interested in filling the same position with the Bears, but it looks like that's not going to happen now.
